equalization of pressure on both
sides of shut-off disc after relief

Seat Ring Replacement (See Figures 4 and 8)
Disassembly:
1. Remove the compression ring (outer ring) by turning
counter-clockwise. Ring should be loose after 2 turns.
2. Remove the seat ring (inner ring) by turning counterclockwise
until the complete assembly can be lifted out of
the manifold body. Discard seat ring. Save compression ring
for reassembly.
3. Thoroughly clean the inside threads of relief valve port with
a wire brush. Be sure all sealing surfaces are clean and free
of scale. Use care not to damage threads.
Reassembly:
1. Deburr the slots in the new seat ring assembly and new
compression ring.
2. Screw the seat ring assembly into the compression ring until
it is flush at top.
3. Apply a light grease to the seat ring body threads.
4. With the shut-off disc under the relief valve port, insert seat
ring and compression ring assembly into the port and screw
in by hand as far as possible.
5. Use a wrench to adjust the depth of the seat ring. The seat
ring should be positioned so that when the shut-off disc is
moved with the handwheel, the shut-off disc remains in
contact with the seat ring for approximately 1 /8" of travel.
6. Turn the handwheel and approach the relief valve port from
both sides with the shut-off disc. Make certain that the shutoff
disc does not hit the seat ring from the side before
seating. Make adjustments if necessary.
7. While holding the seat ring assembly in place with a wrench,
tighten the compression ring.
Bleeder Valve Assembly Replacement
Disassembly:
1. Using a 1" hex wrench, turn the bleeder valve body counterclockwise.
Remove and discard assembly.
2. Visually inspect the port in the manifold body. Remove any
debris or scale using care not to damage threads.
Reassembly:
1. Open new bleeder valve assembly to a fully back-seated
position by turning bleeder valve knob counter-clockwise.
See Figure 5.

2. Apply a light grease to the male threads on the bleeder valve
body.
3. Thread the bleeder Valve body clockwise into the manifold
assembly. Tighten using a 1" wrench on bleeder valve body.
Re-Installing the Manifold Assembly
If the manifold was removed from the container, replace with the
following steps.
1. Install a new manifold gasket onto either manhole cover or
neck flange. See Figure 2.

2. Mount the manifold so that the handwheel is located in a
position that permits the greatest ease of reading and
operation.
3. Tighten the stud nuts gradually in a sequence of alternate
and opposite rotation (1,5,3,7,2,6,4,8). See Figure 7.
