(23). Lightly apply "Food Grade Anti-Seez" to
the body cap threads and install into the body.
Tighten to 25-30 ft.-lbs.
15. Re-orient the body in soft jaw vise to where the
large body opening faces upward. For Model
PA1: hold on to threaded end of plug so it does
not fall out of the inlet, bottom connection.
16. Use appropriate end connection and loading
source to pressurize the inlet of the body
between 50 and 100 psig. (Inlet pressure will
help hold the plug in place during the assembly
and assure best plug position for regulation.
17. Continue to hold the plug (10) while placing the
pusher plate (17) over the threaded end of the
plug. Be sure to correctly orient the pusher plate
so the o-ring groove faces up.
18. Slide the o-ring (18) over the threaded end of
the plug and into the groove of the pusher plate
19. While still holding the plug, place the diaphragm
(16) over the plug down on top of the pusher
plate (17). Make sure the diaphragm is lying
flat and is centered inside the body.
20. Place travel stop (15) over the diaphragm,
ensure that the grooved side faces the
diaphragm.
21. Lubricate stabilizing o-ring (13) with "Food
Grade Anti-Seez" and slide it over the top
edge of the pressure plate and into the groove.
Position the backup ring (13) above the
stabilizing o-ring in the pressure plate groove.
Place the pressure plate over the threaded end
of the plug.
22. Place the lock washer (12) over the threaded
end of the plug and then thread nut (11) onto
the same end of plug.

23. Using a small adjustable wrench, hold the plug
in place by the flats at the top. Use a 7/16"
wrench to tighten hex nut to approx. 50 in.- lbs.
24. Release all pressure that was applied to inlet
of the regulator.
25. Place the range spring (8) on top of the
pressure plate. Then place the spring button
(7) and ball (6) on top of range spring. Apply
a small amount of "Food Grade Anti-Seez" to
top of ball.
26. Lubricate the outside threads and flat bottom
surface of spring chamber (2) and threads of
adjusting screw (4) with "Food Grade Anti-
Seez".
27. Thread the spring chamber into the body and
tighten to 75-100 ft. lbs.
28. Place the nameplate below the jam nut (5)
and thread adjusting screw into the spring
chamber until nut (5) makes contact with top
of spring chamber.
29. Use appropriate end connections and test per
Cashco Spec #S-1526 for Pressure Reducing
Regulators.
NOTE:
Regulators are not tight shutoff
de vic es. Even if pressure builds up be yond
set point, a reg u la tor may or may not develop
bubble tight shutoff. In general, tighter shutoff
can be ex pect ed with com po si tion seat.
30. For Model PL1: pressurize body with air
and spray liquid leak de tec tor to test around
body cap (6) and body (1) for leakage. Test
pres sure should be a mini mum of 100 psig
(6.9 Barg) at the inlet.
31. Return to Section IV for start up.
