Southbend 3SRV8-1 Relief Valve 3/4" 35 PSI

The Southbend 3SRV8-1 Safety Relief Valve 3/4" 35 PSI works by automatically opening when the internal pressure hits the 35 psi setpoint, and it releases the excess fluid or steam in the system. It operates on a spring-loaded system that returns to the closed position when the pressure goes below the threshold to ensure system equilibrium during the operating cycle. It is mounted on a pressure-containing equipment outlet line or at specific security discharge points which are usually mounted on boilers, pressure vessels, or pressurized piping assemblies where controlled venting is needed when set pressure conditions are met as part of a pressure-secure assembly.
