Pressure Reducing Control

Surge Anticipator and Pressure Relief Valve with Reverse Flow Control

The CLA-VAL 52-03R is typically installed near the pump on a discharge line to a tank. When pumping systems are started and stopped gradually, harmful surges do not occur. However, should a power failure take place, the abrupt stopping of the pump can cause dangerous surges in the system which could result in severe equipment damage.The CLA-VAL 52-03R anticipates the surge by opening on the low pressure wave in order to be fully open on the returning high wave diverting the excess pressure.The valve will let reverse flow pass through the valve if upstream pressure fall under atmospheric pressure.
