Zurn Industries’ pressure regulator valve (PRV) ZW209Q with downstream Surge Protection provides both functions in one valve. This PRV will rapidly close to protect the downstream piping system if there is a sudden surge in downstream pressure.
The pressure reducing pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position ensuring a constant downstream pressure within tight tolerances.
The valve holds downstream pressure to a constant value while providing protection against sudden pressure surges when demand suddenly stops. Pressure gauges, wye strainer, isolation valves, and epoxy coating come standard to simplify start-up and maintenance. Globe, reduced port globe, and angle bodies are available. 150 class flanged, 300 class flanged, grooved, and threaded end connections available for installation versatility.
