Emerson Fisher 92S, Instruction Manual

Page: 13 / 24

For NPS 2-1/2, 3 and 4 / DN 65, 80 and 100 body
sizes, install the plug spacer (key 33), baffle
(key 13), O-ring, washer, spring seat and piston
spacer (keys 38, 34, 32 and 11). Then, install the
cylinder (key 17), spring (key 12) and secure with
piston (key 24), piston ring (key 25), with its open
end pointing out, piston ring retainer (key 26) and
stem nut (key 15).
For the NPS 1, 1-1/2 and 2 / DN 25, 40 and
50 body sizes, lock the stem nut (key 15) in place
with a cotter pin (key 16), but do not fold the pin
ends up on top of the stem since this can interfere
with loading pressure registration through the top
stem passage.
5. Install the main piston cage assembly with
attached parts into the body. Coat the edge of the
main cylinder (key 17) with sealant and install a
new cylinder gasket (key 18) onto this edge.
6. Install a new body gasket (key 19) onto the
appropriate edge of the body.
7. For NPS 1, 1-1/2 and 2 / DN 25, 40 and 50
body sizes, install the stem seal (key 22) onto the
cylinder spacer (key 21) in the orientation shown
in Figure 5, and secure with the stem seal retainer
(key 23). Coat the serrated edge of the spacer
with sealant and install the spacer edge-side-down
over the bottom cylinder.
8. For NPS 1, 1-1/2 and 2 / DN 25, 40 and 50 body
sizes, coat both serrated edges of the top cylinder
(key 17) with sealant, install new cylinder gaskets
(key 18) on these edges and install the cylinder.
9. For NPS 1, 1-1/2 and 2 / DN 25, 40 and 50 body
sizes, install the top piston ring (key 25) with its
open end pointing out, ring retainer (key 26) and
stem (key 20) on the top piston. Secure these
parts with the lockwasher and hex nut (keys 40
and 41). Install the top piston plus attached parts
stem-first through the stem seal until the top stem
contacts the bottom stem.
10. Install the body flange (key 2) on the body, and
secure with the cap screws (key 3, not shown) for
a cast iron body or with the stud nuts (key 4) for a
steel body.
11. Install the pilot and connect all tubing as shown in
Figure 6.
12. When all maintenance is complete, refer to the
Start-up section to put the regulator back into
operation and adjust the pressure setting.
