Servicing of valve assemblies
DISASSEMBLY OF THE OUTLET VALVE
1. Disassemble paint level from the plant.
2. Dismantle/Remove outlet valve assembly.
3. Figure 15
Unscrew the outlet valve seat 14 on the piston rod 8.
Clean and inspect the parts. The piston has a special
thread locking/sealing patch. Do not remove this
patch. This patch allows for disassembly/assembly
procedures before it is necessary to apply Loctite® to
the thread.
4. Figure 16
Remove packing and glands from piston rod.
5. Clean and inspect parts for wear or damage, replace
parts as necessary.
Teflon O-rings (1, 6, 10, 11, 12, 14) will always be
replaced in this procedure.
RE-ASSEMBLY OF THE OUTLET VALVE
1. Mount piston in a vice.
2. Place ball into piston.
3. Install packings, wipers and glands.
4. Apply Loctite® to valve seat threads, if special thread
locking/sealing patch is insufficient. (Normally good
for 4 repacks.)
5. Apply 75 Nm torque when screwing valve seat into
piston.
DISASSEMBLY OF THE INLET VALVE
1. Relieve pressure following "PRESSURE RELIEF
PROCEDURE" steps.
2. Figure 17
Disassemble inlet valve. Clean and inspect O-ring.
You may need to use a pick to remove O-ring.
RE-ASSEMBLY OF THE INLET VALVE
1. Reinstall inlet parts in correct order. Reverse inlet
seat 22 if necessary.
2. Run the machine at pressure for several minutes,
inspect for leaks and proper operation.
