GENERAL OPERATION
General:
The body for an ACV is a Globe 13112A-22 Series valve,
hydraulically operated by a diaphragm assembly (the only
moveable part). The body is made up of three major
components:
a)
Body
b)
Diaphragm assembly
c)
Cover
The body contains a removable seat.
Operation:
The diaphragm consists of nylon insertion with neoprene material and the diaphragm assembly is guided top and bottom
by a precision-machined stem. The diaphragm is never used as the seating surface.
A disc retainer fully retains a resilient nitrile disc, which forms a drip-tight seal with the valve seat when pressure is applied
above the diaphragm.
Operating pressure is separated from line pressure due to the diaphragm assembly forming a sealed chamber in the
upper section of the valve.
No glands or ‘O’ rings assure long life and maintenance-free operation.

MACK SPECIAL PURPOSE TRIMS
MACK ACV valves are available with special trims for critical service applications.
Existing Mack ACV’s can be retrofitted with alternative trims without removing the valve from the line.
‘V’ PORT TRIM
Mack Valves ‘V’ port trim is a precision engineering
trim designed to alter the ratio of flow to valve lift. The
effect of this is to give greater control particularly at
the low end thus enabling the valve to control over a
much wider flow range and in certain cases
eliminating the requirement for a second smaller
valve installed in a by-pass application to cater for low
flow conditions.
ANTI-CAVITATION TRIM
Mack Valves anti-cavitation trim is designed for use
where the valve is operating within the cavitation zone
(refer cavitation chart).
Valves working in the cavitation zone are susceptible
to severe damage, excessive noise and vibration.
Mack Valves anti-cavitation trim consists of a pair of
high precision double sliding cages manufactured in
Grade 316 stainless steel with proportioned orifices to
enable a high degree of flow control.
These cages control the point at which the cavitation
recovery occurs and allow it to dissipate harmlessly.
Contact your nearest Mack Valves outlet for help in selecting the correct trim for your application.

The valve will remain wide open when the inlet
pressure is greater than the outlet pressure.
When a reversal of pressure occurs, control tubing
from the outlet side conveys pressure to the top of
the diaphragm, forcing the valve to close.
Optional opening and closing speed controls on the
pilot tubing assist in surge prevention.

MACK PRESSURE REDUCING VALVE
Valve Selection
Select a valve of a size suitable for the expected flow
and required pressure loss. Incorrect sizing of valves
can produce problems. Before selecting a valve,
consider
initial
pressure,
reduced
pressure,
and
maximum and minimum flow rates.
Excess velocities considerably shorten the life of any
valve.
Stainless steel trim should be specified if high velocities
are expected. If inlet and outlet pressures on cavitation
chart are within the cavitation zone, valve requires the
use of Mack Valves anti-cavitation trim.

MACK PRESSURE REDUCING VALVE
Model No. 13112A-18
Typical Function & Application
‰
The Pilot Control Valve senses the downstream pressure in the main valve and allows flow to occur when the
downstream pressure is lower than the spring setting on the pilot valve.
‰
When the downstream pressure is higher than the spring setting on the Pilot Control Valve, both the pilot control
and main valve close.
‰
The Pilot Control Valve reduces pressure from main and keeps pressure constant, regardless of intermittent
demand.
‰
The 13112A-18 Valve maintains an accurate downstream pressure regardless of fluctuations in the inlet
pressure of the valve.

MACK PRESSURE REDUCING & CHECK VALVE
Typical Function & Application
‰
The valve maintains an accurate downstream
pressure regardless of fluctuating demand or
variations in inlet pressure.
‰
The valves prevents a reverse flow through the
main valve should the downstream pressure
exceed the upstream pressure.
‰
The valve positively prevents a backflow
occurring should the down stream pressure
increase above the set point.
‰
The valve closes slowly on pump shutdown.
‰
Careful selection of the size of the valve is
paramount as excessive velocities considerably
shorten the life of any valve. Stainless steel trim if
high velocities are expected.

OPERATION
♦
Automatically controls the height of the top
water level with a one-way or two-way flow
through the main valve.
♦
Designed to control the high water level in
reservoirs.
♦
The action of a three-way diaphragm
actuated pilot valve opens the main valve to
allow the reservoir to fill or close it when the
reservoir water level reaches the top water
level. The valves are non-throttling and
remain fully open until the reservoir reaches
full capacity.

MACK MODULATING FLOAT CONTROL VALVE
Model No. 13112A-33
Typical Function & Application
‰ Performs the function of equalising
variations in supply and demand to
maintain a constant level.
‰ The 13112A-33 series may be
arranged to balance either the in-flow
or out-flow rates in a tank by offering
both valve closing and opening on a
rising liquid level.
‰ Changes in the liquid level cause the
float control to shift, changing the
pressure in the cover of the main
valve producing a different extent of
opening.

MACK REMOTE SENSING PRESSURE REDUCING CONTROL
Typical Function & Application
‰ The 410 pressure reducing valve automatically reduces a
higher inlet pressure to a lower outlet pressure.
‰ It is a direct acting, spring loaded, diaphragm type valve that
operates hydraulically or pneumatically, and is designed to
sense pressure from a remote point.
‰ As a pilot control it will cause the main valve to hold a
relatively constant down stream pressure at the remote
sensing point.
Spring Setting Range:
50 – 500 kPa
Spring part no. 1935-0H3-062
501 – 1300 kPa
Spring part no. 1935-0K3-062
1301 – 2100 kPa
Spring part no. 7018-026-062
Adjustment Procedure
Pressure adjustment is made by turning the adjustment
screw to vary the spring pressure on the diaphragm. The
greater the compression on the spring, the higher the
pressure setting.
1.
Turn the adjustable screw clockwise to increase
downstream pressure.
2.
Turn the adjustment screw anti-clockwise to
decrease downstream pressure. When pressure
adjustment is completed, tighten lock nut on
adjustment screw and replace cap.
Model No. 410
48
MACK PRESSURE RELIEF CONTROL
Adjustment
Pressure adjustment is made by turning the adjusting
screws to vary spring pressure on the diaphragm. The
greater the spring compression, the higher the pressure at
which the valve opens.
Turn the adjusting screw clockwise to raise the pressure
relief setting. The adjusting screw is protected by a bronze
housing, which is drilled to accommodate a lead-seal wire.
The pressure relief control valve can be adjusted to provide
a relief setting at any point within the range stamped on the
nameplate.
Installation
Install as shown in look up diagram of complete valve
assembly; be sure to connect control tubing as shown. This
control may be installed in any position. Allow sufficient room
to make pressure-setting adjustments when installation is
complete.

Description
Disassembly of the valve requires no special tools. The
control does not need to be removed from the line. Back out
adjustment screw to remove spring tension before removing
cover.
Inspection
Inspect valve disc for scoring, or embedded foreign particles.
Inspect diaphragm for excessive wear and other damage.
Check all parts for damage, corrosion, excessive wear and
minimal deposits.
Repair &Replacement
The Mack pressure relief control is a direct acting, springloaded diaphragm type relief valve. It may be used as a selfcontained valve or as a pilot control for the main
(13112A-22) valve. It opens and closes within very close
pressure limits.
Replace all parts, which are damaged. When ordering
replacement parts, be sure to specify catalogue number, and
all nameplate data.
Operation
Reassembly
The valve is normally held closed by the force of the
compression spring above the diaphragm. When the
controlling pressure exceeds the spring setting, the disc is
lifted off its seat, permitting flow through the control. When
controlling pressure drops below spring setting, the spring
returns the control to its normally closed position.
Reassembly is the reverse of disassembly; no special tools
or jigs required.
Test Procedure
No testing of the pressure relief control is required prior to
reassembly to the main valve.
49
MACK DIFFERENTIAL CONTROL
Model No. 405
Typical Function & Application
‰ The 405 differential control closes when
controlling
pressure
exceeds
the
predetermined setting.
‰ The valve is designed for use in conjunction
with Model 13112A-11 rate of flow valve and
Model 13112A-12 combination pressure
reducing and rate of flow valve and operates
within very tight pressure limits.
‰ The valve is actuated by the differential
produced across an orifice plate in the main
line. Accurate control is assured as very
small changes in the controlling differential
produces immediate corrective action of the
main valve.
‰ Rate of flow is adjustable by varying the
spring load on the control.

‰ When reservoir pressure increases to the set point,
the control shifts interconnecting ports (S) and (1).
This pressurises the cover of the main valve, which
