The pressure regulating valve is shown in Figure 6. The pressure regulating valve can be adjusted to bypass
fluid at a given pressure setting while the pump continues to run.
1. Adjusting The Pressure Regulating Valve
NOTE: For easy adjustment of the pressure regulating valve, always adjust the pressure by increasing
to the desired pressure setting.
A. Loosen the locknut (B) on the pressure regulating valve, and back the adjusting screw or knob (A) out
a few turns by turning it in a counterclockwise (CCW) direction. This will
decrease
the setting to a lower
than desired pressure.
B. The pump must be completely connected electrically and hydraulically. Start the pump.
C. Slowly turn the adjusting screw or knob (A) in a clockwise (CW) direction. This gradually
increases
the
pressure setting. When the desired pressure is reached, lock the adjusting screw (A) in position by
tightening the locknut (B). Shut off the pump.
IMPORTANT: The pressure range is from 1,000 to 10,000 PSI (70 to 700 BAR) depending on the pump
model.
