PENBERTHY MODEL FHS AUTOMATIC LIQUID HEATING SYSTEM
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
5. Reassembly of valve sub-assembly.
a. Assemble the components as shown in
Figure 5 and per instructions below.
b. With the valve body resting on a work bench,
inlet side down, insert the seat gasket and
seat inside body making certain that the
seat is properly seated.
c. Insert the cage over the top ring of the seat.
d. Place the two (2) gaskets over the top ring of
the cage in proper order.
e. Insert the bonnet/body gasket into the body.
f. Make certain that the stem is properly
installed in the bonnet (refer to Section 4 -
Installation) and replace the bonnet into the
body.
g. Hold the valve firmly and replace the cap
screws through the bonnet and wrench
tighten.
h. Replace the valve body into the piping
system using a PTFE tape or equivalent on
all male tapered pipe threads as shown in
Figure 3.
i. Connect air hose and regulator to
diaphragm actuator and pressurize to fully
open valve (100%).
j. Place the actuator yoke over the threads of
the valve bonnet, making sure to place the
yoke nut and valve position indicating disc
over the stem while doing this.
k. Thread the valve stem into the actuator
connector rod approximately 6 full turns.
l. Tighten the yoke nut down finger tight and
check to see if the yoke is seated against the
valve bonnet.
m. If the yoke is not seated against the valve
bonnet, thread the valve stem further into
the actuator connector rod until the yoke
is seated against the valve bonnet, then
tighten the yoke nut in place.
n. Tighten the stem connector nut against the
valve position disc and actuator connector
rod.
o. Slowly reduce the air pressure to the
actuator to close the valve. At 0 psig
(0 kPaG), the valve position indication disc
should indicate that the valve is closed. If
the disc goes below the 0% open mark on
the actuator scale, this indicates improper
adjustment.
p. To adjust the disc position, increase the
air pressure to the actuator to raise the
valve 20-40% open. Then loosen the stem
connector nut a few turns and turn the stem
counterclockwise one turn, tighten the stem
connector nut and release the air pressure.
This procedure should be repeated until the
indicating disc is exactly indicating 0% open
for the valve.
q. Remove the air hose from actuator
r. Reconnect the air line connection to the
actuator.
s. Refer to Section 5 - Operation, when
returning the FHS to service.

- Invoice number and date
- Process conditions (pressure, flow rates, tank
shape, etc.)
- A brief description of the problem
- Trouble shooting procedures that failed
If attempts to solve your problem fail, you may
request to return your FHS to the factory for
intensive testing. You must obtain a Return
Authorization (R.A.) number from Emerson
before returning anything. Failure to do so will
result in the unit being returned to you without
being tested, freight collect. To obtain an R.A.
number, the following information (in addition to
