Machine slow or weak under load
This valve sets the main hydraulic pump output from the pump controller. A sticking or failed valve leaves the pump at the wrong output: the machine feels slow, bogs the engine, or lacks digging force.
Pump fault on the monitor
A pump solenoid or pump control fault points at this valve or its wiring. Check the plug, the harness and the controller output before replacing it.
Coil test
Unplug the valve and measure the coil resistance. An open or shorted coil means the valve must be replaced.
Fitting tips
Relieve hydraulic pressure, clean around the valve before removing it, fit a new O-ring lightly oiled, and torque the four flange bolts evenly.
