Check Valves

Check Valves are UL listed and FM approved.

Check Valves, in 1Â-½ and 2 in. sizes, can be installed horizontally or vertically. They are rated up to 250 psi water working pressure and include tapped opening for system draining. Both 1½ in. and 2 in. are UL and ULC listed in threaded or grooved styles, and are FM approved in the grooved configuration as both single check valves and anti-water hammer check valves.
