FEATURES:

CF port (Controlled Flow) - Flow coming from the CF port is pressure compensated and proportional to the current
received by the coil. Flow can vary from closed to wide open.
 EX port (Excess Flow) - Flow coming from the EX port is also pressure compensated. Note: When zero current is
received by valve entire flow will exit valve via the EX port.
MOUNTING & ADJUSTMENT INSTRUCTIONS:

Mounting – Valve can be mounted in any orientation. Valve must be mounted on a flat surface. Special attention should
be paid to not bend or twist the casting when mounting. Doing so may cause the compensator spool to bind, causing
valve to fail. It is recommended to install washers between casting and mounting surface.
 Manual Override Adjustment – The flow rate from the valve can be manually adjusted. This feature can be used if
power to the coil is lost.
To manually adjust controlled flow: First, remove the 7/16” acorn nut. Next, loosen the 7/16” jam nut. Finally,
turn the override screw clockwise with a flat head screwdriver to manually adjust the flow out of the CF port
.
 Relief Adjustment (If equipped) –Relief valve can be set anywhere within the range of 750 psi to 3000psi.
To adjust relief pressure: First, loosen the relief lock nut and then turn the relief adjustment fitting clockwise to
increase the pressure setting. Both the relief lock nut and relief adjustment fitting accept a 1.375” wrench. EX port
MUST be plumbed back to tank for relief function to operate.
FREQUENTLY ASKED QUESTIONS:
Q: Can the CF port be blocked or plugged?
A: No. If the CF port is blocked or plugged for any reason the compensation spool will attempt to compensate for increasing
pressure, and shift thus blocking the EX port as well, and rendering valve inoperable. DO NOT BLOCK CF PORT.
Q: Can the EX port be blocked or plugged?
A: The EX port can be blocked or plugged, but doing so requires a pressure compensated or load sense pump. Plugging the
EX port may create instability issues that can be remedied by switching the compensator spool to a different spool. (Part #
