The 350 Double Check Valve Assembly is used in low health hazard, non-potable water applications for protection against both backsiphonage and backpressure of polluted water. A favorite for irrigation contractors, the patented and innovative EZSwap® removable pressure vessel allows for simple, cost-effective maintenance and repairs, straightforward line flushing, quick winterization, and water savings. Its stainless steel shut-off valve handles, hardware, and struts are corrosion-resistant and the durable UV resistant reinforced nylon EZSwap Pressure Vessel resists corrosion and mineral build-up to better withstand harsh outdoor conditions.
