UL/FM Check Valves

Mueller® UL listed, FM approved check valves are of the gravity operated, swing check design. They are rugged in construction and simple in design, allowing for removal of all parts through the top of the valve for inspection or replacement without removing the valve from the line. Mueller check valves are bossed on both sides of the body for connecting by-passes and have a drain plug at the bottom under the inlet end for attaching a drain valve, and are available with either rubber or bronze disc facings.
