CLASS DLO(S)-2 CAGE-RETAINED TRIM CONTROL VALVES
DESIGN FEATURES
Leslie’s Class DLO(S)-2 cage-retained control
valves are designed for general purpose control of
clean, dirty, viscous or corrosive liquids, as well as low
to medium pressure, clean or dirty steam and gas service.
The cage-retained seat design eliminates the need
or use of any threaded internal parts insuring ease of
maintenance and parts replacement even after years
in corrosive service. Top entry design also permits
easy access to all internal parts for inspection or
maintenance without removal of the valve from the
pipeline. The DLO-2 class also features the highest
Cv capacity of any comparable single seated valve in
the industry providing maximum flows and minimum
pressure losses.
Two point stem guiding provides rigid plug guiding
and makes these valves especially suited for controlling dirty liquids or steam.
Through-bolted bonnet on cast steel and stainless
steel valves, in lieu of bonnet studs, makes valve servicing easy, even after many years of service in corrosive environments.
Body Materials
Two Point Stem Guiding
Class DLO(S)-2 control valves are
available in several body materials to handle a wide variety of applications.
Standard body materials include cast iron,
carbon steel (DLOS-2), and 316 stainless
steel (DLOS-2). Other materials are available on request.
The heavy duty stem is guided at
the top and bottom of the bonnet by
two guide bushings. Unlike single
point guiding, this method minimizes
trim wear and seat leakage caused
by plug deflection and vibration.
Stem guiding also eliminates any
possibility of pumping of fluid as can
happen with post guided globe
valves by eliminating the bushing
cavity where media can become
trapped then pumped through the
packing.
Tight Shut-Off
Seat material
choices include 316
stainless steel seats
with Stellite* alloy hardfacing providing ANSI
Class IV or V shut-off,
316 stainless steel
optional. An optional
316 stainless steel seat
with a PTFE insert provides ANSI Class VI
bubble-tight shut-off
and Class IV metal-tometal back-up.

End Connections
DLO-2 Series valves
are available in ANSI 125#
250#, and (DLOS-2) series
in 150# and 300# class
body ratings. Choice of
standard end connections
include threaded, socket
weld, butt weld and raised
face flanged. DIN flange
end connections optional.
Page B2
CLASS DLO(S)-2 CAGE-RETAINED TRIM CONTROL VALVES
Cage-Retained Trim
Leslie Class DLO-2 valves feature no internal
threaded parts making them ideally suited for handling
corrosive fluids and insuring ease of parts removal
even after years of service. The non-threaded seat ring
is rigidly clamped into the valve body by the bonnet
and the seat retaining cage.
Reduced Trim Options
Class DLO-2 Series
control valves offer up to
five different trim sizes
and flow capacities for a
given body size.
Reduced trim options
provide controllable Cv’s
from .02 to 57. For metering
applications,
Microtaper* trim provides
Cv’s as low as .01. Multiple trim selections provide optimized valve sizing, allow for future capacity increases, control
of body velocities and
easy correction of oversized valve problems.
One Piece Stem/Plug
One piece plug and
stem eliminates any possibility of separation due
to vibration and ensures
correct plug/stem alignment at assembly for
accurate seating and
tight shut-off.
APPLICABLE INDUSTRY STANDARDS
All Leslie control valves are 100% factory tested and
serialized. Leslie Controls’ quality assurance program is
accredited and certified to ISO 9001†. All Leslie control
valves are also designed, built and tested to meet the
following industry standards.

risk of damaging the 8 micro-inch sealing surface.
Bolted Yoke
Conventional valves with the lock-nut actuator
mounting design are easily ruined and scrapped due to
corrosion. Leslie valves use a 4-bolt actuator mounting design which guarantees ease of disassembly no
matter how corrosive the environment.

PACKING CONFIGURATIONS
LIVE-LOADED PTFE - V-RING
(PRESSURE)
PTFE/GRAPHITE
DOUBLE-PTFE WITH BLEED,
PURGE
Live-loaded PTFE V-ring packing
provides the most maintenance free
stem seal. The V-ring packing is both
pressure energized and live-loaded by a
316 Stainless Steel spring to automatically compensate for packing wear.
Maximum service temperature is 460˚F
(238˚C). V-rings can be inverted for vacuum service.
Split rings allow packing replacement without removal of actuator.
Graphite impregnated PTFE provides
500˚F (260˚C) service temperature, better memory and sealing than pure PTFE
rings, lowered stem hysteresis, and is
ideal for fluids that contain suspended
particles.
Two sets of packing rings separated
by a 316 stainless steel lantern ring can
provide zero stem leakage and prevent
fugitive emissions. Bonnets are 1/4"
NPT drilled/tapped for connection of
lubricators, water seals, bleed-off or
positive inert gas purge. Maximum
temperature 500˚F (260˚C).

Spring and Diaphragm Actuators
Leslie spring and diaphragm actuators are available for Class DL0-2 valves in three different sizes,
from 35 to 85 square inches in diaphragm area, both
in direct (fail open) and reverse (fail closed) action.
Leslie actuators feature long strokes, constant
effective diaphragm area for linear response and high
operating pressures (to 60 psi) to minimize actuation
costs. Leslie actuators also feature a 4-bolt yoke
mounting method (not bonnet lock-nut) to insure ease
of disassembly, even after years in corrosive service.
As standard options, a variety of accessories
can be yoke mounted including:
· Positioners, Pneumatic/Electro-Pneumatic
· I/P Transducers
· Proximity or Limit Switches
· Position Transmitters
· Solenoid Valves
· Integral Filter/Regulators
A manual override hand operating device (HOD)
is also available for manual valve operation or use as
a valve travel limit stop. See product data sheets
10/0.2.1 and 10/0.2.2 for complete specifications.
