Low Head Loss Stainless Steel Double Check Valve Assemblies with Integral Butterfly or OSY Shutoffs - Deringer 20X/20GX

Ames Deringer™ 20X and 20GX Double Check Valve Assemblies are designed to prevent non-health hazard pollutants from entering the potable water supply system caused by backpressure and/or backsiphonage conditions. Deringer 20X 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 20GX 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).
