WPRV Williams Pressure Reducing Valves
The WILLIAMS FIRE & HAZARD CONTROL Pressure Reducing Valve (WPRV) maintains constant pre-set inlet pressure for use in conjunction with the Around The Pump (or comparable) foam systems. It allows any firefighting water pump to produce suction side foam at virtually any positive inlet pressure.
