Pressure relief valve adjustment
In order to adjust the set point of the Pressure Relief valve, the module’s three ball
valves must be in the closed position.
Start by screwing completely the back pressure adjustment screw (19').
Start the pump and wait until fluid passes through the pressure relief valve into the
evacuation port. Use the adjustment screw (19) to obtain the desired pressure set point.
Once the desired set-pressure is obtained, tighten the counter nut (20), stop the pump
and slowly open the evacuation valve to release the system pressure.
Proceed with the back pressure valve adjustment.
Notes:
 The maximum torque to be applied on the adjustment screw (19 & 19') and
counter nut (20 & 20') is 35 in-lb.
 Turning the screw clockwise increases the set pressure.
