The 975XLST Reduced Pressure Principle Backflow Assembly is used on potable water applications for high health hazard protection from both backsiphonage and backpressure of contaminated water into the potable water supply. The 975XLST features all stainless steel body construction that is ideal for systems utilizing liquids corrosive to copper alloys, including medical diagnostic equipment, food processing, distilleries, breweries, and similar applications. It is also ideal for applications requiring lead-free valves. Utilizing the same corrosion-resistant internals as the Model 975XL, the 975XLST comes standard with full port QT ball valves and includes threaded FNPT end connections.
