Description

This 10 inch lead free MasterSeries double check valve backflow preventer assembly protects potable water systems from non-health hazard pollutants due to backsiphonage or backpressure. Its ductile iron body is coated with ArmorTek, an advanced epoxy system designed to resist microbial and exposed metal corrosion. Featuring non-rising stem shutoff valves and stainless steel check components, this assembly is designed for drop-in replacement in N-pattern or Z-pattern installations. It operates at a maximum working pressure of 175 psi and is suitable for temperatures from 33°F to 140°F. The assembly complies with low lead requirements and multiple industry standards including ASSE 1015, UL, and FM.
