Bermad Excessive Pressure Shut-Off Valve - Series 979-4/Model BC-794-P

Implementing a pressure safety solution on a PRV Station is highly recommended in order to protect the downstream piping from experiencing unsafe excess pressures. The Victaulic Series 979-4/Bermad Model BC-794-P Excessive Pressure Shut-Off Valve is one of three pressure safety solutions. Used in systems designed with PRV Stations featuring a redundant line, this valve "fails closed," stopping all water supply downstream of the malfunctioning PRV, and signaling the building management system (BMS). Since there is a redundant line, the supply will be uninterrupted. 

The Series 979-4 valve handles pressures up to 250 psi; the Series 979-4HP valve handles pressures up to 400 psi. Both versions of the valve are available in 1 1/2 - 8"/DN40 - DN200 sizes, with grooved (standard), female threaded NPT, or flanged ends.
