The 4" 375ASTDA Reduced Pressure Detector Assembly 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.
