8.1.4 Pressure Override (POR) Valve
Pressure Adjustment (Option for
180 Frame Size)
The Pressure Override Valve is explained in Sec.
2.4.10.
1. Install two 1000 bar (or 10,000 psi) pressure
gauges in the high pressure gauge ports (M1 and
M2). Install a 50 bar (or 1000 psi) pressure gauge
in the pump charge pressure gauge port (M3).
2. Start the prime mover and operate at normal
speed.
3. With the pump operating at approximately 20%
displacement, load the work function and note the
pressure as the POR valve operates (pump dis-
placement reduces to “zero”).
4. Adjustment of the pressure override setting is
made by loosening the lock nut with a 9/16 inch
hex wrench and turning the adjustment screw with
a 3/16 inch internal hex wrench. The POR setting
should be at least 50 bar (750 psi) below the high
pressure relief valve setting of the multi-function
valves for proper operation.
5. Following the adjustment, torque the lock nut to 43
Nm (32 lbf•ft).
6. Shut down the prime mover and remove the
gauges and install the gauge port plugs.
