Description

A relief valve set up to 15,000 PSI for the temporary relief of excess system pressure. Once the pressure of the pump reaches a pre-designated pressure the valve will release the pressure. This stainless body and spring-loaded mechanism is a rugged tool and stays set to the pressure set by the factory. The tool maintains its integrity in heat or cold and other harsh environments.

*Please specify set pressure when ordering.
