InstallatIon and MaIntenance InstructIons
3.2.6
Place inner spool spring onto the inlet
seat. Place outer spool spring over the inner
spool spring onto the inlet seat. Place a small
amount of Loctite 242 on the threads of the
inlet nozzle. Thread on the piston connector
and tighten, compressing the springs.
3.2.7
Carefully install piston seal into the
groove of the piston with the opening of the
seal facing outward. Carefully insert the piston
into the piston plate. Place a small amount of
Loctite 242 on the threads the piston connector.
Thread the piston connector onto the piston and
tighten using the wrench flats on both parts.
3.2.8
Place body/piston plate seal between
these parts and, very carefully, guide the
exhaust seat stem of the upper assembly
through the bushing, dome spool seal and
stem seal. (Be careful not to scratch or dent
the exhaust nozzle seating surface). Also, be
careful not to damage the dome seal. This
assembly will stop when the exhaust seat
comes in contact with the exhaust nozzle.
install the cap screws through the piston
plate and into the body and tighten to 18 ft-lb
(24 N-m). Place roll pin (41) into pin locator
hole located near the edge of the piston plate.
3.2.9 Lift lever
3.2.9.1
Thread the lift rod bushing onto the lift
rod. Place a light coat of Fluorolube LG-160
oil or equivalent to the contact surface of the
bushing and bottom spring washer (24). Slide
the lifting rod with bushing through the bottom
spring washer.
3.2.9.2
Apply a light coating of Fluorolube
LG-160 oil or equivalent on the top of the
sense piston where the lifting rod bushing will
contact. Place the bottom washer, bushing
and lifting rod assembly on top of sense piston
followed by stacking the spring and the top
spring washer. Lower the bonnet over the
spring and spring washer stack until the flange
rests on the piston plate with the pin engaged
in its respective hole in the bonnet outer rim.
Apply a light coating of Fluorolube LG-160 oil
or equivalent on the outer threads of the body.
3.2.9.3
Slide the bonnet ring over the bonnet
and thread onto the body capturing the bonnet.
Thread the ⅜” bolt used during disassembly
of bonnet into the threaded hole in the bonnet
ring (do not bottom). Use the bolt as a handle
to tighten the ring into place. Or, use a spanner
wrench and tighten using the unthreaded hole.
3.2.9.4
Place a small drop of Loctite 242 or
equal on the threads of the bonnet ring screw,
thread into the side of the bonnet ring and
tighten.
3.2.9.5
Apply a light coating of Fluorolube
LG-160 oil or equivalent on the internal threads
of the bonnet and the threads of the pressure
adjustment screw (25). Screw the adjustment
screw into the bonnet until it contacts the top
spring washer. Thread the adjustment screw
nut (26) down the adjustment screw until the
nut contacts the bonnet and then secure hand
tight. Go to Section 6 for adjustment of pilot set
pressure.
3.2.9.6
Thread spindle nut (33) onto the lift rod
(27) just enough until 2 full threads on lifting
rod is visible below the spindle nut. Do not
thread in hex nut (34) yet. Place cap (29) on
bonnet. Guide lifting lever through cap under
the spindle nut and attach to cap using the
lever pin. Adjust the spindle nut until there is a
1
/
16
inch [1.5 mm] minimum of play between the
lifting lever and the spindle nut. The spindle nut
may be adjusted by removing the lifting lever
pin and lifting lever.
3.2.9.7
Once the spindle nut has been set,
remove cap (29) and thread in hex nut (34) into
lifting rod and tighten against spindle nut (33)
by firmly holding spindle nut with adjustable
plier. ensure that the hex nut is attached firmly
to the spindle nut. replace cap on bonnet and
position the lifting lever opposite of the valve
outlet and install the cap screws. install lock
wire from lever pin to cap screw to bonnet ring
screw.

location.
every Series 5200 valve comes with a
condensate trap. The PTFe O-ring between
the body and bushing is replaceable. remove
the bushing from the body, discard the used
O-ring and replace with the new O-ring from
the soft goods kit. Lubricate bushing thread
with Fluorolube LG-160 oil or equivalent. Screw
the bushing back into body and tighten to
80-100 ft·lbs.
every Series 5200 valve comes with a backflow
check valve on the pilot exhaust. The check
valve seal is replaceable. remove the fitting
from the check valve body. remove the flow
washer and ball. Using an O-ring pick, remove
and discard the check valve O-ring. Lightly
lubricate a new O-ring from the soft goods kit
with Dow Corning Molykote 33 silicone grease
or equivalent. install O-ring in the body groove
and replace the ball and flow washer in the
correct order. reinstall the fitting to the check
valve body using PTFe tape.
The Series 5200 valve can be ordered with a
field test device to check set pressure while the
relief valve is in service. This device includes a
shuttle and indicator. The seals can be replaced
in these devices. To replace the seals, loosen
the bushing from the body and remove the
shuttle and seals. Lightly lubricate all seals
with Dow Corning Molykote 33 silicone grease
or equivalent. install the new seals in the
locations shown in Figure 8. install the shuttles
in the bodies and tighten the bushings.
