Plunger valve

The Henry Pratt Series 300 Plunger Valve is a flow control valve that reduces cavitation and stagnant water creation to help water systems improve operational safety, efficiency and flow control. The new valve contains a valve actuator mechanism that provides non-linear closure with precise surge resistance and effective control ranges as high as 96 percent. The plunger's O-ring seal, which is located outside of the cavitation zone — and four hard faced cylinder support guides — work together to help minimize wear and provide the valve with a longer operational lifespan.
