Adjusting The Pressure Relief On The Control Valve
•
IT IS NOT necessary to adjust the pressure relief on replacement valves to allow
proper operation of the divider. Note: Oliver’s valves are normally preset at the
factory and adjustment IS NOT necessary. Should it become necessary to change
the pressure relief setting follow the two steps given below.
•
Connect a pressure gauge at the quick disconnect provided on the high-pressure
hose at the pump fitting. Note: a pressure gauge test kit can be purchased from
Oliver Products Co. at additional cost.
•
With the pump running use the calibrating screw in the bottom of the valve to set the
pressure at 800 PSIG secure the calibrating screw in place with the locking nut once
the proper pressure has been achieved.
