The relay
valve
(5) is the device
which
controls
the air
flowing
to the brake
cylinders.
It will
apply,
maintain
or release
the air pressure
in the cylinders
in response
to the control
valve
commana.
To apply
the brakes,
the relay
valve
takes
air from
the
supply
reservoir
and
directs
it to the brake
cylinders.
It can
control
this pressure
from only
a few pounds
up to emergency
brake
pressure,
depending
upon
the control
valve
signal.
To release
the
brakes,
the relay
valve
closes
off the reservoir
supply
to the
cylinders,
and vents
the cylinders
to the atmosphere,
releasing
the
brakes.
Should
a brake
cylinder
leak and
thus
loose
pressure,
the
relay
valve
will
admit
more
air in an effort
to maintain
the
pressure.
Brake
cylinders
(6) are responsible
for forcing
the brake
shoes
against
the wheels
or discs
to stop
the train.
Admitting
air
into
the cylinders
applies
the brakes.
When
this
air is released,
a
large
spring
forces
the piston
back,
releasing
the brakes.
The above
explanation
is highly
simplified
from
a car's
actual
brake
system.
The other
devices
are added
to improve
the
performance
of the simple
system
into
that required
to smoothly
and
safely
stop
a car.

Operation
As part
of the HEP upgrade,
E-5 decelostat
systems
were
installed
on all disc
brake
equipped
cars,
replacing
the old
mechanical
pneumatic
units.
Provisions
were

During

braking,
especially
on slippery

the brake
system
is capable
of sliding

This
is especially
true of disc

cars;

treads
making
them
less
likely
to slide.
The E-5 unit
uses
a speed
sensor
mounted
on one journal
of
each
axle to measure
axle speed.
It does
this
by counting
the teeth
on the gear
of the EE bearing
axle
end cap as they pass;
each
tooth
produces
an electrical
pulse.
The E-5 controller
is a tiny
computer
which
compares
the speeds
of the 4 axles
and also
the rate
at which
the speeds
change.
Before
a wheel
goes
into
a slide,
it creeps
along
the rail.
The E-5 system
senses
this creep
before
a slide
occurs,
and activates
the A-end,
B-end

Since
the decelostat

it prevents

General
Maintenance
The truck
wiring
is effectively
the only
maintenance
item of
the system.
Care must
be taken
to inspect
the truck
areas
upon
arrival
of the train
at the terminal.
Any damaged
wiring
or sensors
should
be repaired
before
dispatching
the car.
An inoperative
wheel
slide
system
can easily
cause
wheel
spalling,
which
is a very
expensive
maintenance
item.
A few minutes
of inspection
and repair
will
save many
thousands
of dollars
in wheel
costs.
If a car
is found
with
badly
spalled
or flat wheels,
check
the decelostat
system
to determine
if it is functioning
properly.
If
the E-5 is functioning,
the problem
is likely
to be the brake
system
itself,
the control
or relay
valve.
When
a car's
wheels
are
to be changed,
first
disconnect
the
speed
sensor
plug
on the axles
to be removed.
Reinstall
the speed
sensors
and gap them
to .020-.030
AFTER
the car is back
on its
wheels.
If the sensor
is ad3usted
i_t,
the gap will
change,
and
may
even contact

gouging
it.

It is imperative
that

react
quickly
for the decelostat
system
to be effective.
Should
a sluggish
valve
be found,
remove
and examine
the valve.
If foreign
material
is
found,
it is likely
that
the entire

A second
circuit
is made
up when
all train
brakes
are released,
giving
a green
light
in the cab.
Whether
the brakes
on a given
car are applied
or
released
is sensed
by two pressure
switches
on each
car,
one per
truck,
connected
into
the brake
cylinder

When
the brake

is above
23 psig

the switches
indicate
the brakes
are applied
on the car.
When
the pressure
on
both

drops
below
i0 psig,
the switches
indicate
the brakes

The

The Salem 700 -1 C0z Gauge and Pressure Switch Tester is an entirely
hand operated, self-contained portable tester, mounted on a companion
holster using C0= as its testing medium. (As shown on front side).
PROCEDURE FOR TESTING:
1. Open needle valve (A) very slowly as you are releasing 900 Ibs.
pressure. If opened too quickly, pressure will build up of 185 psi
and vents out the safety relief and manual vent valve. This protects the gauge from damage, but wastes C02
2. When desired pressure is reached, GENTLY CLOSE needle valve
(A). Pressure may be manually reduced by pressing safety relief
and manual vent valve (D).
.
For fine VERNIER adjustment use displacement valve (B). This
can be used for one or more Ibs. adjustment throughout the entire
185 lb. range.
If you have no leaks in the gauge complex, one cartridge should
test 30 to 50 puges.
PROCEDURE TO CHARGE TESTER: (Remove from holster.)
1. Depress safety relief and manual vent valve (D) to assure that all
pressure is released before removing knurled chamber cap (E).
2. Remove knurled chamber piercing cap (E) which should be screwed out with fingers only - no tools needed.
3. Remove spent C02 cartridge (G).
4. Before inserting new C02 cartridge, be sure that needle valve (A)
is closed.
.
Insert
new
C02
cartridge(G) in handle chamber.
6. Before replacing chamber piercing cap, examine and be sure
piercer (F) is backed out against shoulder (I).Turn roll pin handle
(J) counter clockwise to accomplish this.
,
Replace chamber piercing cap (E). No Tools needed - Screw in
Finger Tight
8. Again check to make sure that needle valve (A) is closed. If it is
not, air will escape out the safety relief and manual vent valve(D).
9. Turn roll pin handle (J) clockwise all the way in to pierce the COz
cartridge then back it out against the shoulder (I). (Counter clockwise). This now charges the tester with C02.
10.
Replace tester on holster. Tester is now charged and ready to
test gauges or pressure switches.

All apparatus
is confined
to the truck,
eliminating
the
need for wire or additional
pipe connections
to the car
body.
While
not a fundamental
part of the brake
equipmeat,
the DECELOSTAT
controller
is a recommended
anti-wheel
slip device
that modifies
the braking
force to
avert
wheel
sliding.
Its function
is to maintain
high
over-all
train retardation
by anticipating
wheel
sliding
and momentarily
moderating
the braking
force so that it
does not exceed
the lowered
rail-wheel
adhesion
existing
when wheel slipping
occurs.
As indicated
on the opposite
page, Fig. 43, the DECELOSTAT
equipment
for a 4-wheel
truck comprises
a
DECELOSTAT
controller
mounted
on the journal
cover
of each axle, and a DECELOSTAT
Valve
mounted
on
the truck transom.
A hose connection
from each DECELOSTAT
controller
leads to a common
pipe connection
to the DECELOSTAT
Valve.
Thus for a conventional
car with two 4-wheel
trucks,
there is required

Valves.
If a wheel slips, the braking
pressure
is softened
and
then restored
to the value of existing
on the other cars of
the train. The operating
cycle provides
instant
moderation-the
reduction
requires less than a second--followed
by a fast but controlled
build-up
of pressure

GENERAL
OPERATION
Sme ucy
When an emergency
rate of brake pipe reduction occurs,
the emergency
valve of the 26C Control Valve is operated to provide a local brake pipe reduction
at the control valve.
This rapid drop of brake pipe pressure operates the control
valve more quickly and delivers
a higher brake cylinder pressure than normally
o Ixalned during se_ine
brake application.
To release following
an emergency
application
after the 26-C Control Valve
quick action chamber has been vented.
The brake pipe is recharged
to position the
26-C Control Valve in release position.
The brake cylinder pressure
is now
released
and the auxiliary
reservoir is recharged.

DESCRIPTION
The 28-C Control
V(dve is a pneumatic
device
designed to function
automatically
in response to
pressure changes to dire{:t a flaw of uir to or from
the brake cylinders
of )o an intermediate
relay valve
on passenger carrying
vehicles.
The 26-C Control
Valve is offered
for application
to passenger cars
operating
in trains NOT EXCEEDING
twenty four
(24) - ninety (90) foot long cars.
The control valve
consists
of a pipe bracket
on which
a service
portion,
an emergency
vent valve portion,
a brake
pipe cut-out
cock
and strainer
portion,
and o
reservoir
release valve portion,
are mounted.
Although not a part of the device ilself, nn auxiliary or
main reservoir,
a control
reservoir,
and a selector
valve volume reservoir
are required to complement
the functions of the 26-C Control Valve.
The auxiliary
or main reservoir

valve when used, when properly
connected
through
porting in the Control Valve.
C.
The function
of the control reservoir
pressure is to
provide a reference force to cause movement of the
service valve in the service
portion of the 26-C
Control
Valve when o reduction
occurs in the
opposing brake pipe pressure.
D.
The selector valve reservoir acts as a stabilizing
volume during the operation of the selector
valve
during quick service and graduated
release operations.

A Graduated Release Cap, which is used to manually
position the valve for Graduated
or Direct
Release,
is located on the service valve portion.
The letters
REL. are cast on the body below the graduated
release, cap. The letters DIR. and GRA. ore cast on
the cap. When the letters DIR. are over the letters
REL., the valve is set for Direct Release; when the
letters GRA.
are over the letters REL., the valve is
set for Graduated
Release.
The cap is set by
removing
the two cap screws and turning the cap so
that either DIR. or GRA. line up with REL. on the
body.
The Selector Valve (designed into the service portion
of the 26-C Control
Valve)
controls
the quick
service function,
provides
for the direct
release
function
when required,
and enables
the control
valve to be satisfactorily
trained with D-22 Type
Brake Equipment
if necessary.
There are four (t4)
positions that this valve may assume during operation of the control valve; these ore Release, Service,
Lop, and Emergency.
The Service Valve Portion contains a service spool
valve, which includes two (2) diapllragms selected
for proper reference
to permit
the development
of
brake cylinder pressure in accordance
with broke
pipe reductions.
An application
valve controls the movement
of the
air from the auxiliary or main reservoir to the brake
cylinder
application
pipe.
Whenever o reduction
in
brake pipe pressure occurs in the control valve, the
service spool valve assembly
moves upward and
opens the application
valve.
The service spool valve
also serves to exhaust,
through the control
valve,
the air pressure of the brake cylinder
application
pipe, whenever the bruke pipe pressure is increased
at the control
valve..
The diaphragm
area ratios,
together with the spring arrangement
included in the
service valve portion, permit stable operation of the
automatic
broke together with proper development
of broke cylinder
pipe pressure to operate satisfactorily with other current
equipment orranqements
of

for:
The service
valve portion
also contains
two (2)
limiting
valves
for the purpose
of limiting
the
maximum
pressure directed
to the brake cylinder
application
pipe during service and emergency
applications.
These pressures are predetermined
by the
load setting of the springs within the limiting
valves.
During emergency
applications
the emergency limit_ng valve is designed to open when the brake pipe
pressure is reduced to a value of approximately
13
to 18 psi, to permit a controlled fast build-up of the
emergency
brake cylinder application
pipe air pressure, then reseat, limiting
emergency
brake cylinder
application
pipe air pressure to o predetermined
value.

The continued
increase of this pressure also effects
a

o point in slight excess of the spring force
within the emergency

piston wilt be moved downward, permitting
the check valve to seat end cut off the

The increased pressure differential
across the
diaphragm
in the selector valve, as a result of
the fast rote of drop in brake pipe pressure,
positions the diaphragm
assembly
and spool
valve to momentarily
provide those functions
obtained during o service applicationi
but, as a
result of the further
travel of the spool valve
into Emergency Position,
the emergency spring
is engaged and Passage 9 is lapped to close the
connection to the selector volume reservoir.
K.
The upward movement
of the service valve
unseats the application
valve to permit auxiliary (supply) or main reservoir
air to flow to the
limiting
valves
and into Passage 16 that is
connected
to the brake cylinder
application
pipe.
(a) Auxiliary (supply) or main reservoir air
flows to the underside of the service
limiting valve spool. Whenever this pressure reaches a point in slightexcess of the
spring load, the spool is designed to move
upward, thus cutting off any further flow
of air through this valve into the brake
cylinderapplicationpipe.
k.
(b) In the design of the 2_;-C Control Valve, a
chamber is provided for brake pipe air in
the emergency limitingvalve,and itisthis
pressure that holds down the limitingvalve
piston.
During initial stages of an
emergency brake application, the emergency limitingvalve willremain closed. As
the brake pipe pressure continues to drop,
and is reduced to a value between 13 and
18 psi in the control valve, the force of the
spring within the emergency limitingvalve
overcomes the force of the brake pipe
pressure on the piston. The piston willthen
move upward, unseating the check valve
and provide an alternate passage for auxiliary(supply)or main reservoirair to enter
into Passage 16 that connects to the brake
cylinderapplicationpipe. During the initiation of an emergency brake application,
the broke pipe pressure drop should be so
rapid that at the time the emergency
limiting valve opens the check valve, the
service limitingvalve isstillopen and not
as yet positioned in itsuppermost position.
The check valve in the emergency limiting
valve will remain open to permit a continued flow of air to the brake cylinder
application
pipe.

The Emergency Valve Portion of the 26-C Control
Valve is so constructed
to allow
quick action
chamber air to exhaust at the same rate that brake
pipe air is reduced
during a service
application.
During o service application
the drop of brake pipe
pressure at o service rate in the spring chamber of
the emergency valve creates a pressure differential
across the diaphragm.
The diaphragm assembly and
spool valve move upward to an intermediate
position
to establish
a connection
between
quick action
chamber and exhaust Choke M. Chokes M and B are
of a predetermined
size and provide a controlled
exhaust of quick action chamber air. The chokes ore
sized to maintain an air pressure that stabilizes
the
spool valve and prevents
the unseating of the high
pressure check valve.
If the broke pipe pressure is reduced at on emergency rate in the control
valve, quick action chamber
pressure will position
the diaphragm
assembly and
spool valve in the extreme upward position.
In this
position, the quick action chamber is now connected
to exhaust Choke M, which provides a blowdown of
the quick action chamber air.
With the spool valve
in the upper position, the stem unseats the pilot
valve and exhausts the air pressure on the top of the
check valve carrier.
Broke pipe pressure below the
check valve end carrier
forces
that valve open,
creating a large opening for a rapid brake pipe air
exhaust.
The check valve in the top cover limits the
volume of air that must be exhausted
at the pilot
valve, thereby permitting
fast opening of the large

stem permitting
supply air (passage 6) to flow into
passage 30 that is connected to the brake cylinder pipe.
Passage 30 is also connected
to chamber "B" on the
spring side of the diaphragm.
The build-up of air at
brake cylinder
pipe pressure in chamber "B" along with
the spring force oppose the movement of the diaphragm
assembly
initiated
by the controlled
air pressure admitted into passage 16. An equalization
of forces across
the diaphragm positions the diaphragm assembly to allow
the check valve to seat and remain in e lop position.
DESCRIPTION
The "J-I"
Relay Valve Portion
Pc. No. 556t_1
is o
diaphragm operated, self-leppinq
valve that functions
to
direct or exhaust air pressure in the broke cylinder pipe
during air broke operation
in accordance
with o broke
cylinder control pressure.
]-he portion is designed to be
mounted on o manifold,
or to e pipe bracket that may be
arranged for either suspension or floor mounting.
Consult your Westinghouse
Air Broke Division Representative for correct
style of mounting
for specific installations.
,x N
The maintaining
feature
of the relay valve portion will
function if pressure fluctuates
in the brake cylinder pipe.
If the pressure in passage 30 as well as the pressure in
chamber "B" drops, the piston stem will move to open the
check valve.
Supply air will then again flow into passage
30 as well as chamber "B" until an equalization
of forces
across the diephrogm is again reached.
The diaphragm
assembly
is then positioned
to permit
the valve
to
reassume o lop position.
A decrease of air pressure in passage 16 (brake cylinder
control) results in a corresponding
decrease in pressure in
the relay valve diaphragm
chamber hA" which causes a
movement
of the diaphragm
assembly and piston stem.
The piston stern is forced
to unseat from the check
valve, permitting
air at brake cylinder
pipe pressure
(passage 30) to flow to atmosphere
at the exhaust port.
A graduated release of brake cylinder air out of passage
30 can be obtained if control pressure in passage 16 is
intermittently
depleted. When an equalization
of forces
• exists across the diaphragm, the valve will again assume
a lap position. The amount of air pressure available for
braking is a function of the pressure in chamber hA".

AND TECHNIQUES
The
use of an air jet, which
must be less than
30
p.s.i.g., to blow parts clean or to blow them dry after
being cleaned with a solvent will cause particles of
dirt and/or droplets of the cleaning solvent to be airborne. Wire brushing may also cause particles of dirt,
rust, and scale to become airborne. These conditions
may cause skin and/or eye irritation.
I)
A controlled
air pressure build-up in passage 16 results in
a corresponding build-up
in pressure on the relay valve
diaphragm in chamber "A" which causes o movement of
the diaphragm assembly
and piston stem.
The piston
stem is forced to close against the check valve which
blanks off passage 30 (brake cylinder) from exhaust. The
check valve is then lifted from its seat by the piston

WABCO
DESCRIPTION
The "J-I"
Relay
Valve Portion
Pc. No. 556298 is a
diaphragm operated, self-lapping valve that functions to
direct or exhaust air pressure in the brake cylinder pipe
during air brake operation in accordance with o brake
cylinder
control pressure. The portion is designed to be
mounted on a manifold, or to a pipe bracket that may be
arranged for either suspension or floor mounting.
Consult your Westinghouse Air Brake Division
Representative for correct style of mounting for specific installations.
The maintaining
feature of the relay valve portion will
function if pressure fluctuates in the brake cylinder pipe.
if the pressure in passage 30 as well as the pressure in
chamber "B" drops the piston stem will move to open the
check valve. Supply alr will then again flow into passage
30 as well as chamber "B" until an equalization of forces
across the diaphragm is again reached.
The diaphragm
assembly is then positioned to permit the valve to
reassume a lap position.
A decrease of air pressure in passage 16 (brake cylinder
control) results in a corresponding
decrease in pressure in
the relay valve diaphragm chamber"A"
which causes a
movement
of the diaphragm
assembly and piston stem.
The piston stem is forced to unseat from the check
valve,
permitting
air at brake cylinder pipe pressure
(passage 30) to flow to atmosphere at the exhaust port.
A graduated release of brake cylinder air out of passage
30 can be obtained
if control pressure in passage 16 is
intermittently
depleted.
When an equalization
of forces
exists across the diaphragm, the valve will again assume
a lap position.
The amount of air pressure available for
braking is a function of the pressure in chamber "A".

The E-3 Brake Application Valve operates when actuated by
air pressure from the conductorts or emergency brake valve
to quickly
vent brake pipe air to atmosphere
at on
emergency rate initiating
an emergency brake application.
The valve consists of o body in which o piston valve and
piston spring ore assembled.
The piston is fitted with o
piston ring, felt oil retainer,
strainer, and strainer plate.
When properly
lubricated,
the all retainer
maintains
o
coating of oil on the cylinder wall. The strainer is designed
to restrict accumulation of dirt on the piston.
IIl.C.
II.
I.
The solvent used for cleaning the parts removed from
the valve must be on oliphatic organic solution, such as
mineral spirits or naphtha, that will dissolve all or
grease and that will permit all parts to be thoroughly
cieoned wlthootabrasion.
2.
The lubricant used to lubricate the piston with retainer
and the piston bush is Triple Valve Oil, AAR Specification M-912, WABCO Specification M-7611-20.
OPERATION
(Refer to the assembly view)
With the brake application valve properly connected to the
brake pipe, brake pipe air normally flows around the outer
face of the piston valve (10), thence through o small port in
this valve to the spring chamber. From the spring chamber,
the air flows through the side connection to the emergency
brake valve.
With air pressure equal on both faces of the
piston valve 10, spring 4 holds the piston valve seated,
sealing the atmospheric opening below the seal 9.
When the emergency brake valve is placed in emergency
position, it permits the air in the spring chamber of the E-3
Brake Application
Valve to escape faster than it con be
_pplied through the part in the piston valve 10. This rapid
nonge in brake pipe pressure moves the piston valve I0 off
s seat providing o large direct opening from brake pipe to
atmosphere so that brake pipe air exhausts at on emergency
rate which,
in turn, signals for an emergency application of
the brakes.

Ih OPERATION
(Referring
to the assembly
view)
2.
When the operating lever of the B-3-C Emergency Broke
Valve is manually rotated to its full operating
position by
means of a cord or other device, and held in this position,
the valve lever is forced downward
to unseat the valve
assembly.
Unseating of the valve assembly causes air
from the brake application
pipe to be vented to atmosphere which in turn signals the brake application
valve or
vent valve to function
for the purpose of exhausting
brake pipe air at an emergency rate.

The WABCO "E-5"
DECELOSTAT
Equipment
is
designed to provide the means for wheel slip control
for a four axle, two truck, passenger carrying
rail
vehicle.
By a momentary
release of braking effort,
which is in excess of that which available
adhesion
will support during friction braking,
the equipment
serves to restrict
flat spotting and other damage to
wheel treads caused by braking in excess of wheelrail adhesion.
Braking effort adjustment is on o per
truck basis, and may be fully operational
for both
service and emergency
braking.
Adjustment
of
effective
frictional retardation
on a per truck basis
is initiated
by each "C-3" DECELOSTAT
Control
Valve.
C,
The "E-S" DECELOSTAT
Equipment
also provides
"zero speed" and "five mile per hour" indications.

Velocity
B.
b.
When a sufficient adhesion is regained to
cause the difference
in velocity to reduce
sufficiently
below an established threshold
value, and this change is transmitted
to
Westinghouse Air Brake Divison electronics, termination
of the "C-3"
OECELOSTAT Control Valve energizafion
should
occur_ permitting
a jerk rate limited reapplication of braking air.
C.
Operation of the "C-3" OECELOSTAT
Control Valve due to velocity
differeNl
detection
takes precedence over an opera
lion clue to rate detection.
However, when
both occur
simultaneouslyy
the velocity
differential
must reduce below the established
threshold
before
"C-3"
DECELOSTAT Control Valve de-energizatlon
is
permitted to occur.
d.
The established threshold
velocity difference is a variable value determined
by the
maximum
wheel diameter variance (due to
wheel wear) translated into "mile per hour"
figures.
For an installation with new 36
inch diameter wheels and possible 3 inch
diameter
tread wear_ the velocity
difference threshold varies from approximately
14 mph at [ZO mph car velocity to approximately 3 mph near zero ear velocity.
SLIP CORRECTION
I.
Rate
a.
b.
Co
4_15
Ourinq Brakinq
The D.C velocity voltage signals are compared, the highest (of all four) against each
individually.
If a velocity
difference
is
detected by Westinghouse Air Brake Division electronics between any two axles that
exceeds an established threshold value, the
difference
in velocity voltage signals will
be of sufficient magnitude to energize the
"C-3" DECELOSTAT
Control Valve on the
truck experiencing the low axle velocity,
thus permitting o release of braking effort
on that truck.
CONVERSION
The shaper and F/A
(frequency
to analog)
converter
portions of the "E-S" Electronics
accepts the four frequency signals and converts
them 1o D.C. analog voltage signals proportional to axle velocities.
The differentiator
portion of the electronics
provides four additional D.C. analog voltage signals proportional
to the rate of change (deceleration or acceleration) of the axle velocities.
Detection
a.
The velocities
of each of the four axles are
registered by inboard, journal mounted, magnetic pickups. By sensing movement of teeth on o
rotating gear, each pickup is intended to produce an A.C. signal output whose frequency
is
proportional to velocity.
.
Differential
Detection
When any axle decelerates
(slips) sufficiently
so that the corresponding deceleration voltage signal exceeds a preset value
equivalent to approximately
-8 mphps, the
"C-3" DECELOSTAT
Control Valve for the
affected
truck should be automatically
energized.
"C-3" DECELOSTAT
Control
Valve energization
signals a release of
braking effort air on that truck.
If the affected
axle accelerates
quickly
through o regain of wheel to rail adhesion
and the resultant acceleration
voltage exceeds o preset value equivalent to approximately +6 mphps_ termination
of energizalion of the "C-3" DECELOSTAT
Control
Valve should occur, permitting
jerk rote
limited reapplicotian
of braking effort air
on that truck.
3.
Regardless,
if the affected axle does not
accelerate
quickly
enough to produce an
acceleration
voltage of sufficient
magnitude (i.e. approximately
+6 mphps) after o
small time period (nominally one second)
has elapsed, the circuitry
is designed to
terminate
energization
of the "C-3" DECELOSTAT
Control
Valve provided a velocity
differential
detection
signal is not
present.

The "E-S" DECELOSTAT

(Refer to Figures I and 2) The Pipe Bracket Portion is
bolted to the truck body and is designed to allow for the
removal and replacement
of the valve portions without
disturbing any pipe connections.
The Pipe Bracket
Portion is normally installed in the broke cylinder air line
so that port I is connected to the brake cylinder side and
port 2 to the air supply source.
(Refer to Figures
I and 2) The "FA-4"
Magnet Valve
Portion, Pc. 527702, is an electro-pneumatic
valve with a
voltage range of 45 to 85 volts.
The nominal voltage is
64 volts, and the maximum operating air pressure is 150
psig. The electric portion of the valve portion consists
of a magnet coil housing (21) containing
a magnet coil

BRAKE

Supply air under pressure enters port 2 of the Pipe
Bracket Portion and flows to the underside of the piston
(9) of the Release Valve Portion and to port 2 of the
Magnet Valve Portion.
With the lower valve (35) of the
Magnet Valve Portion held off its seat by the force of
the spring (32), air also flows through port 2A to the top
of the release valve piston (9).
Since the pressure is
balanced on both faces of the piston, the force of spring
(6) will hold the piston (9) seated.
Supply air under
pressure also flows to the spring side of the check valve
(49), located
in the Pipe Bracket Pqrtion, by means of
port IA of the Release Valve Portion.
A drilled passage
in the check valve (49) allows a controlled
build-up of air
pressure to the Brake Cylinders
through port I of the
Pipe Bracket Portion.
When o wheel slip occurs and the external wheel slip
sensing device transmits an electrical signal to energize
the "FA-4" Magnet Valve Portion, the armature and stern
of the Magnet Valve Portion are pulled downward.
The
lower valve (35) will be seated and the upper valve (35)
will be unseated to connect port 2A to port IA.
This
exhausts the air on top of the release valve piston (9) by
means of ports 2A and IA and also through the exhaust
passage EX in the Pipe Bracket Portion.
Air pressure
build-up under the piston (9) will overcome the force of
the spring (6) end move the piston upward.
This action
cuts off supply air under pressure at port 2 of the
Release Valve Portion
and opens port IA to exhaust.
Brake Cylinder air under pressure can, therefore,
vent
rapidly through port I of the Pipe Bracket
Portion,
through the Check Valve (49) and out port IA of the
Release Valve Portion.
When the wheel slip ceases, the external
wheel slip
sensing device should signal the "FA-4" Magnet Valve
Portion to de-energize.
This will permit the spring (32)
to return the armature
and stem of the Magnet Valve
Portion to the upper position.
The upper valve (35) will
be seated and the lower valve (3S) will be unseated to
reconnect
port 2 to port 2A. This redirects
the flow of
supply air from port 2 to the top of the Release Valve
Portion piston (9) through port 2A and balances the air
pressure on both faces of piston (9) to allow the force of
the spring
(6) to move the piston downward.
The
downward movement of the piston cuts off the exhaust
of brake cylinder air from port IA end permits supply air
under pressure at port 2 to flow through port IA; through
the drilled passage in the check valve (49); out port I of
the Pipe Bracket Portion; and restores brake cylinder air
pressure at o controlled rate.

Because

Keep the
