Deringer 50X/50GX
Low Head Loss Stainless Steel Reduced Pressure Detector Type II Assembly Backflow Preventers with Integral Butterfly or OSY Shutoffs
Ames Deringer™ 50X and 50GX Reduced Pressure Detector Type II Assemblies are designed to prevent non-health hazard pollutants and hazardous contaminants from entering the potable water supply system caused by backpressure and/or backsiphonage conditions. Deringer 50X features integral Eccentric-seal™ butterfly shutoff valves for a short lay length, XL body and checks for lower head loss, and Dual-action™ checks for high performance at low- and high-flow rates. Deringer 50GX has all of the same great features, but with OS&Y shutoff valves. The Type II bypass is used to monitor unauthorized water usage and is primarily required on fire sprinkler systems.
Either may be installed under continuous pressure service to protect against both backpressure and backsiphonage. Maximum working pressure: 175psi (12 bar).
