3.17.5 Safety relief valve – Relative adjustment

Adjustment of the standard setting pressure is performed at the factory.

Note! When testing the safety relief valve mounted on the pump, make sure the pressure never exceeds the set pressure of the valve + 2 bar.

To adjust the standard opening pressure, proceed as follows:

1.Loosen the tap bolts (7310).

2.Remove cover (7050).

3.Take the measurement of dimensions of H.

4.Read spring ratio in the below table and determine the distance over which the adjusting bolt (7320) must be loosened or tightened.

Note!

Spring ratio p/f depends upon the dimensions of the spring. It is recommended to check the dimensions prior to adjusting the pressure.

When the safety relief valve is not functioning properly, the pump must immediately be taken out of service. The safety relief valve must be checked by your distributor.
