Product Details

Zurn Industries 4-375ASTDABG

The 4'''' 375ASTDABG Reduced Pressure Detector Assembly with grooved end butterfly valves with integral supervisory switch 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.
