SECTION I – INSTALLATION
1. VALVE POSITION
Install control valve in the highest horizontal line
of piping in an accessible location and with
arrow on side of valve body in direction of fluid
flow. Control valve may be placed in any
position, but upright is preferable for ease of
maintenance.
Figure 1 - Typical Installation Expand as
required for fluid flow
2. PROBLEM PREVENTING
PROCEDURES
• Provide removal space above, below and
around control valve for easy removal of
parts during maintenance. See Dwg.
10/9.4.1 or 10/9.4.3 for dimensions.
• Blow or flush out pipelines thoroughly
before installing control valve.
• Protect control valve and following
equipment with a SELF-CLEANING
STRAINER.
• Install stop valves and gauges in inlet and
outlet lines to provide means for checking
adjustment and operation of equipment.
• Provide proper inlet and outlet drainage in
steam service to prevent water hammer or
possible erosion in equipment.
• Adhere to good piping practice. Install a
bypass around the control valve.
3. Connect operating medium tubing from
ontrol pilot, instrument or loading device to
c
diaphragm chamber connection of control
valve or to valve positioner, if one is in use.
Maximum allowable operating pressure for
diaphragm actuators is 60 psig.
4. Recommended Piping for Control of
ompressible Fluids at Values of 25% or
C
Less of Inlet Pressure.
The piping system must be adequately
designed and supported to prevent
Expand outlet pipe to twice control valve inlet
pipe size. Use tapered expander.
• Connect control pipe for control pilot ahead
of outlet stop valve and at least 2’ to 3’
downstream from end of expander.
• Make control pipe connection at least 18” to
2’ from outlet stop valve, any elbow or other
flow direction changing fitting.
Figure 2 - Typical Control Valve Station for
Control of Compressible Fluids at 25% or
Less of Inlet Pressure. Expand further as
required for fluid flow.
NOTE: Where sensing impulse is taken 2’ to 3’
downstream from control valve (expander),
dimension “A” minimum of 6’ to 10’ will
provide lowest noise and velocity factors,
accurate pressure sensing and reasonable
bypass length.
CAUTION!
SECTION II – OPERATION
1. Close inlet and outlet stop valves.
2. Check that control valve responds properly
rough rated travel in relation to changes in
th
operating pressure on the diaphragm. Rated
travel is shown by position of travel
indicator on valve stem relative to travel
indicator scale on yoke.
3. Manually operate control valves fitted with
manual operating devices through rated
travel to check freedom of movement.
Return manual operating device to its
standby position.
4. Place control valve in operation in
ccordance with instructions furnished with
a
control pilot or operating device.

SECTION III –
MAINTENANCE
To reduce maintenance time refer to proper
drawing and follow steps shown below for
applicable operation.
RENEWING VALVE PLUG STEM
PACKING
(See Fig. 3, Fig. 4 and 5)
Renew valve plug stem packing if control valve
has been in service beyond normal maintenance
and packing shows signs of wear. Wear will be
indicated by leakage at the packing gland. Minor
leakage of graphite packing can be corrected by
tightening the packing flange.
Over-tightening of the packing flange
adjustments can cause erratic operation of
Where LESLIE (BRAIDED TEFLON
GRAPHITE) packing is in use, additional
packing rings can be installed to overcome minor
leakage without dismantling the control valve or
breaking valve plug connection.
Shut down inlet and outlet stop valves and check
that valve body is not under pressure. Remove
nuts and lift packing flange and packing bearing
a sufficient height on valve plug stem to apply a
split packing ring around diameter of valve plug
stem. Lower packing bearing over the new ring,
lower packing flange and tighten sufficiently
with nuts to stop leakage.
To replace LESLIE “TEFLON” packing set or a
complete GRAPHITE 11 packing set, the control
valve must be dismantled.
Installation of Stem Packing
Stuffing box interior and valve plug stem must
be clean, smooth and free from imperfections
that may cause new packing to leak.
CAUTION!
RAIDED PTFE/GRAPHITE TYPE
B
PACKING
Figure 4 - Installation Sequence
1. Place metal ring in stuffing box making sure
it bottoms in box followed by spring and
second metal ring. Install bottom Teflon
adaptor chevron, four Teflon packing
chevrons and top Teflon adaptor chevron in
accordance with Fig. 6.
2. Install packing follower, packing flange and
uts. Tighten stuffing box nuts until
n
follower bottoms on bonnet.

LAMINATED GRAPHITE PACKING
Packing tools are available from Leslie Controls
and should be used to insure proper installation
of packing. Packing tool reference numbers are
shown on Dwg. 10/0.5.9, which also shows how
to make the tools.
Figure 6 - Installation Sequence
INSTALLATION
Place spacers and packing rings over stem and
into packing box in order shown on drawing, one
at a time, seating each firmly and using care not
to tear rings on the stem threads. Adjust packing
gland nuts equally-finger tight plus 1/6 turn (one
flat of nut).
ADJUSTMENT
During start-up some leakage may be observed.
Do not readjust packing-allow at least 15
minutes for pressure/temperature stabilization to
occur. If leakage continues adjust a maximum of
1/6 turn at a time. If pressure is raised
considerably, the packing may leak slightly. Do
not readjust-leakage will stop when new
pressure/temperature stabilization is reached.
BREAK-IN
For best results it is recommended that after
packing installation and adjustment the valve be
fully stroked approximately 20 times to break-in
the packing and reduce stem friction.
Injury or death can occur due to failure to
completely isolate valve from all sources of
pressure before beginning disassembly. Do not
proceed until valve has been completely isolated
from the process and vented to atmosphere.
DISASSEMBLY OF ACTUATOR FROM
VALVE BODY ASSEMBLY
(See Fig. 6, 6A, 7 and 9 in Appendix)
WARNING
1. Close inlet and outlet stop valve and relieve
all pressure from piping involved. Remove
all compression from adjusting spring(s).
2. NORMALLY OPEN VALVES-DLO(S)-2.
Relieve air pressure from diaphragm of
actuator. Remove the tubing from upper
diaphragm case.
3. NORMALLY CLOSED VALVES-
DDLO(S)-2. Supply sufficient air to the
actuator diaphragm to keep valve plug from
touching seat while disengaging valve plug
stem from actuator stem.
4. Loosen valve stem nut. Use wrench on plug
stem flats and turn valve plug out of actuator
stem until stems separate. Remove the
tubing from lower diaphragm case.
5. Remove cap screws holding actuator to
onnet and lift off actuator.

5. Remove bonnet gasket (8), seat retainer (5),
seat ring (4) and seal (3). If necessary,
remove seat ring by forcing a wooden dowel
into seat bore and lifting.
CLEANING
1. Clean all parts thoroughly. Polish valve
plug stem with crocus cloth. It should be
smooth and free of scratches in packing
area. Use approved, non-residue forming
solvent for cleaning. Wipe dry with clean
cloth.
2. Inspect all parts and replace any excessively
orn or damaged part.
w
3. Install a new packing set of braided Teflon
graphite or Teflon chevron rings as shown
on packing installation sketch Fig. 3, 4 or 5.
See previous section on renewing valve plug
stem packing.
4. The packing bearings have a long wearing
life material which under normal usage
should not require replacement, however, if
damaged or worn the packing bearing (12)
and/or the bonnet (6) must be replaced.
(Lower bearing in bonnet is not supplied
separately.)
5. The gasket (8) and seal (3) should be
eplaced each time the valve body
r
subassembly is disassembled for cleaning.
All LESLIE control valves are made of the finest
material obtainable, time-tested and backed by
over seventy-five years of know-how.
Machining is done by expert craftsmen and each
valve is inspected and service tested before
shipment to you.
REASSEMBLY VALVE BODY
SUBASSEMBLY LAPPING VALVE PLUG
AND SEAT
1. Insert raised face of seat ring (4) into seat
retainer cage (5) and place these into bore of
valve body bridge.
2. Place new bonnet gasket (8) into body
ecess.
r
3. With light pressure and turning motion
a
ssemble valve plug (2) to the bonnet (6)
being careful not to damage bearings or
packing set (17).
4. Apply very thin film of superfine lapping
compound to the valve plug seating surface.
5. Assemble bonnet (6) complete with valve
plug (2) to valve body (1) applying nuts (10)
only finger tight to studs or bolts (11). The
bonnet acts as a guide when grinding valve
plug.
6. Use wrench on flats of valve plug stem for
rning valve plug (2). Do not bear down on
tu
valve plug stem when lapping. Weight of
parts is sufficient to cause lapping action.
7. As lapping progresses lift valve plug off seat
occasionally and rotate 45˚ to keep
compound evenly distributed. Remove all
traces of compound after lapping. Excessive
lapping should be avoided.
8. Remove bonnet nuts (10), bonnet assembly,
and all body assembly parts. Then remove
all traces of lapping compound from both
valve plug (2) and seat ring (4). Check that
a fine continuous ring of contact has been
made on both seats. The contact ring should
be visible but without depth.
9. Apply silicone grease to seat ring seal (3)
nd insert seal into groove of seat ring (4).
a
10. Insert raised face of seat ring (4) into seat
retainer cage (5) and place these into bore of
valve body bridge. Seat ring (4) sealing face
must be firmly seated in place.
11. Place the bonnet gasket (8) in body recess
and add the bonnet assembly. Apply nuts
(10) to bolts or studs (11) and tighten evenly
for metal to metal joint.
12. Place actuator back on bonnet. CAUTION:
For reverse acting actuators only, air
pressure must be supplied to the diaphragm
chamber sufficient to cause actuator stem to
lift its full travel so valve plug threads may
later be engaged.
13. Place packing flange (13) with concaved
ide of hole facing down thru window of
s
6
actuator over valve plug stem and bolts (9)
to top of packing bearing (12). Secure with
two nuts (7) finger tightened.
14. Secure Actuator flange to bonnet flange with
Cap Screws.
15. With wrench on flats of valve stem, lift
valve plug (2) and with counter-clockwise
motion engage threads in upper stem (31) of
actuator until valve plug can be turned no
more.
SETTING VALVE TRAVEL
CLASSES: DLO-2 AND DLOS DIRECT
ACTING ACTUATOR
(See Fig. 7 in Appendix)
1. Connect controlled air line to diaphragm
ase connector.
c
2. Supply 3 PSIG air pressure to actuator
diaphragm.
3. Compress actuator spring by turning spring
adjustor (35) until travel indicator (37) just
starts to move when air pressure is raised
above 3 PSIG.
NOTE: Alternately add compression and check
starting pressure slightly above 3 PSIG until
correct adjustment is attained. After each check
return air pressure to 3 PSIG.
4. Actuator spring preload adjustment can be
ade either with or without pressure in
m
valve body. Once correct compression is
made no further adjustment is necessary.
5. With valve plug and coupling threads
engaged supply 20 PSIG operating pressure
to actuator diaphragm. Valve will move to
closed position. Observe travel obtained as
shown by travel indicator and indicator
scale. Read- just as follows:
6. OVERTRAVEL – If travel is too great,
loosen stem locknut and turn valve plug
stem out of coupling the amount necessary
to obtain correct travel.
7. UNDERTRAVEL – (Travel is too short)
T
his is not possible if prior step 15 was done
and correct parts were used.
8. When correct travel has been obtained
reduce operating pressure sufficiently to
move valve plug away from seat ring. Then
turn valve stem one full turn out of upper
stem threads. Secure locknut.
9. The one full turn toward the seat ring, made
fter obtaining travel, provides the positive
a
closing force required to obtain tight valve
closure. In all cases be sure to make this
final adjustment.
10. Tighten locknut. Reconnect operating
medium tubing from the sensing element or
manual loading device to the diaphragm
case.
SETTING VALVE TRAVEL
CLASSES: DDLO & DDLOS REVERSE
ACTING ACTUATOR
(See Fig. 9 in Appendix)
1. Connect controlled air line to diaphragm
case connection.
2. Supply 3 PSIG air pressure to actuator
iaphragm.
d
3. Compress actuator spring until travel
indicator begins to move when air pressure
is raised above 3 PSIG.
NOTE: Alternately add compression and check
starting pressure slightly above 3 PSIG until
correct adjustment is attained. After each check
return air pressure to 3 PSIG.
4. The valve plug is closed against upward
fluid thrust by actuator spring force. Total
compression placed on actuator spring must
be sufficient to provide the 3 PSIG preload
plug force required to close the valve.
5. If preload adjustment is made with no
pressure in valve body, then, when the
control valve is placed in operation,
additional compression must be placed on
the actuator spring to provide valve closure
force. With proper adjustment valve will
7
close tightly and will not begin to open until
the 3 PSIG operation pressure is exceeded.
NOTE A: A control valve which has been
adjusted to provide 3 PSIG starting pressure
plus valve closure force (with pressure in body)
will have a considerably higher start-pressure
than 3 PSIG, when tested at 0 body pressure.
NOTE B: Air pressures quoted are relative.
Actual pressures required in operation may vary
with pressure drop conditions existing and/or
actuator springs used.
6. Loosen lock nut. Apply air to diaphragm.
urn valve plug stem into upper stem
T
threads until valve plug is out of contact
with seat ring, when air is removed from
diaphragm. Then turn valve plug stem out
of coupling threads until valve plug just
contacts seat ring again.
7. Supply sufficient operating pressure to
actuator diaphragm to move valve plug
away from seat ring. Then turn valve plug
stem one full turn out of actuator upper stem
threads. Diaphragm disc determines travel.
With proper diaphragm disc correct travel
will result from adjustment.
8. OVERTRAVEL – If travel is too great,
loosen and turn valve plug stem out of upper
stem (35) and the amount necessary to
obtain correct travel.
9. UNDERTRAVEL – If travel is too short,
osen lock nut and turn valve plug stem
lo
further into upper stem (35) the amount
necessary to obtain correct travel.
10. When correct travel has been obtained
increase operating pressure sufficiently to
move valve plug away from seat ring. Then
turn valve plug stem one full turn out of
upper stem threads.
11. The one full turn toward the seat ring, made
after obtaining travel, provides the positive
closing force required to obtain tight valve
closure in single ported valves. In all cases
be sure to make this final adjustment.
12. Tighten locknut. Reconnect operating
edium tubing from the sensing element or
m
manual loading device to the diaphragm
case.
