The 6'''' 375ASTDACFM Reduced Pressure Detector Assembly with cubic feet metered bypass is used in high hazard, fire protection applications to protect against both backsiphonage and backpressure of contaminated water. The 375ASTA features a quality 304L grade stainless steel valve body and access covers for added corrosion-resistance, and an incorporated metered bypass for detecting leaks and any unauthorized water use. Its short lay-length is ideal for installation in compact spaces, while its improved flow characteristics work well for lower-pressure systems. The 375ASTDA comes standard with flanged end OS&Y gate valves, and multiple options for end connections are available for added versatility.
