Low Head Loss Stainless Steel Reduced Pressure Zone Assemblies with Integral Butterfly or OSY Shutoff - Deringer 40X/40GX

Ames Deringer™ 40X and 40GX Reduced Pressure Zone Assemblies  are designed to prevent hazardous contaminants and non-health hazard pollutants from entering the potable water supply system caused by backpressure and/or backsiphonage conditions. Deringer 40X features integral Eccentric-seal™ butterfly shutoff valves for a short lay length, XL body and checks for lower head loss, and True-Seal™ and Dual-action™ checks for high performance at low- and high-flow rates. Deringer 40GX has all of the same great features, but with OS&Y shutoff valves.

Either may be installed under continuous pressure service to protect against both backpressure and backsiphonage. Maximum working pressure: 175psi (12 bar).
