5.8.2 Disassembling the Static Valve Body
1. Remove the nut installed in each side of the valve body:
a. Using a 5/8-in open-end wrench
or socket, remove the nut on the
inlet side of the valve body.
b. Remove the seal backup ring
and the filter from the inlet side
(they may fall out on their own).
Save the seal backup ring. You
can discard the filter.
c. Using a large flathead
screwdriver, remove the nut on
the piston side of the valve body.
Do not use a sharp object inside the valve body. Any scratches on the
valve body will prevent a proper seal and allow leakage.
