6-2.3 Valve Disassembly (3")
Note: Refer to Figure 6-3 for items.
1. Remove the valve with the siphon tube from the cylinder.
2. Remove the O-ring and examine it for cuts and nicks;
replace if necessary. Before reinstalling the O-ring, ap-
ply lubricant.
3. Remove the valve cap, spring and piston assembly.
Note: Remove all internal components of the FM-200
valve from the top of the assembly. However, if
there is excessive piston O-ring friction, the siphon
tube may have to be removed and the piston as-
sembly pressed out from the bottom.
4. Remove the O-rings and examine them for cuts and
nicks; replace if necessary. Examine the O-ring
grooves for foreign matter. Before reinstalling the
O-rings, apply lubricant.
5. Examine the exposed surface of O-ring for nicks and
cuts. Also, ensure that the O-ring protrudes a minimum
of 0.020 in. (0.5 mm) above the conical seating sur-
face of the piston assembly. Replace this O-ring if nec-
essary by removing the seat retainer. Before
reassembling, apply lubricant to the O-ring.
6. Examine the pilot check for any evidence of bending or
other damage. Depress the check and make certain it
snaps back freely. Replace pilot check if necessary.

Note: The items refer to Figure 6-1.
1. Install an O-ring in the piston groove.
CAUTION
!
Make certain the Teflon
®
back-up ring is below
this O-ring as shown in Figure 6-2.
2. Press the piston (Item 6) back into the valve body.
3. Install the spring.
4. Install the O-ring (Item 1) onto the groove in the valve
cap, screw the cap into the valve body and torque to
250 in. lb. (28.2 N-m).
5. If the siphon tube had to be removed to disassemble
the valve, wire brush the siphon tube threads to re-
move the old Loctite
®
residue.
6. Apply a film of Loctite
®
primer to the siphon tube threads
and allow three to five minutes to dry.
7. Apply a film of Loctite
®
sealant to the threads and rein-
stall the siphon tube.
8. Install the O-ring onto the valve neck groove, screw
the valve and siphon tube into the cylinder, and torque
