Manifold Assembly Components
System Relief Valve
The System Relief Valves are cartridges that can
be removed from the manifold (using 1 3/8"
wrench) for inspection or replacement. These
valves are interchangeable in either side of the
manifold, providing the pressure settings are the
same. The first two (2) digits of the pressure
setting are stamped on the end of the valve.
The relief valves are factory set and
should not be disassembled further.
When replacing, torque the cartridge to 30- 70 ft. lbs.
The Shuttle Valve can be removed for inspection
by removing the two (2) hex plugs (using 1"
wrench) and sliding out the springs, spacers. and
spool. These parts are interchangeable and can be
installed from either side. When assembling be
certain the spacers are placed between the spool
and springs. Torque the hex plugs to 60-100 ft.
The spool and manifold are matched
and cannot be replaced separately.
Charge Relief Valve
To inspect or replace the Charge Relief Valve,
remove the hex plug (use 1" wrench) and the
spring and poppet.
Remove the shims from the counter bore of the
plug. Do not alter these shims unless new parts
are used, in which case adjusting the valve setting,
by shimming, is necessary. To install, insert the
poppet, spring, shims and plug. Be certain the
shims are in place in the plug.
