C200-NRS-GXG 10

This 10 IN lead free stainless steel double check valve backflow preventer assembly has NRS groove by groove gate valves that work well in limited headroom situations. Ideally suited for referenced cross-connections identified as non-health hazard continuous pressure applications, it prevents the backflow of contaminated water into the potable water supply and protects against backsiphonage and backpressure. The easy maintenance assembly consists of positive seated thermoplastic independently operating torsion spring check modules, non-rising stem resilient seated gate valves and top mounted test cocks. The temperature range is 33 to 140 degrees F (0.5 to 60 degrees C). The maximum working pressure is 175 psi (12.1 bar).
