Table 10. Type ACE95Sr Diagnostics Table: Cv 20 through 60, Inlet Pressure Range Spring 51 to 120 psig (3,5 to 8,3 bar)
5. Press the lower cage (key 35) and upper cage (key
40) together to ensure the groove in the lower cage
engages the bead on the rolling diaphragm (key 38).
Note
Ensure that the rolling diaphragm bead is
positioned so that it sits in the groove of
the lower cage (see figures 8 and 9). If it
does not, the rolling diaphragm was
installed upside-down in Cage Sub-
Assembly step 2.
6. Remove the lower cage (key 35).
7. Lubricate the piston (key 37) and lower cage (key
35) groove.
8. Install the pilot spring (key 36) into the piston (key
37) and re-install the lower cage (key 35).
9. Hold the pilot sub-assembly together and insert it
into the bonnet (key 17). Press firmly (the bonnet O-
rings will offer resistance).
10. Press the poppet stem. It should freely move up
and down. If it does not, repeat the procedure to this
point to determine the cause.
Note
Use soft-jawed pliers to restrain the main
valve (key 25) while applying Loctite
#222 to the threads of the screw (key 20).
Main Valve Sub-Assembly
1. Prepare the main piston (key 25) by installing the
plug and O-ring (keys 22 and 23) with the screw (key
20) and lock washer (key 21). Apply Loctite
#222 to
the screw threads.
2. Install the main valve spring (key 26), spring shim
(key 34, 25-50 psig, Type ACE95 only), and spring
guide valve (key 49, 25-50/51-120 psig, Type ACE95Sr
only) into the piston (key 25).
3. Place the main valve sub-assembly (piston, spring,
and plug (keys 25, 26, and 22)) into the body (key 18).
4. Place an O-ring (key 19) into the body (key 18).
Body Sub-Assembly
1. Place the bonnet (key 17) onto the body (key 18)
and main valve (key 25).
2. Press firmly to seat the bonnet O-ring joint. If you
are performing assembly operations for the ACE95Sr,
attach the bonnet (key 17) to the body (key 18) with
four cap screws and lock washers (keys 50 and 51).
