Watts Reduced Pressure Detector Assemblies, Stainless Steel 0438623

The Watts Series 994RPDA Reduced Pressure Detector Assembly is designed to prevent backsiphonage and backpressure of hazardous materials into the potable water supply, making it suitable for health hazard applications. It features a stainless steel construction that provides long-term corrosion resistance and strength while being half the weight of competitive designs, which can reduce installation and shipping costs. The assembly includes a pressure differential relief valve located between two positive seating check valves, ensuring reliable operation. The check valves are made from thermoplastic with stainless steel components, utilizing a single torsion spring design to minimize pressure drop. The bottom-mounted relief valve is equipped with a balanced rolling diaphragm, eliminating sliding seals and reducing maintenance costs. The assembly is compact, allowing for smaller enclosures, and includes two resilient shutoff valves and four ball-type test cocks. It operates effectively within a temperature range of 33¬8F to 110¬8F (0.5¬8C to 43¬8C) and has a maximum working pressure of 175 psi (12.1 bar). This assembly is particularly beneficial for installations requiring compliance with water authority containment programs and is capable of detecting underground leaks and unauthorized water use.
