The Tyco® Model CV-1FR is a compact and rugged swing-type unit that enables water flow in one direction and prevents flow in the opposite direction. A resilient elastomer seal facing on the spring-loaded clapper ensures a leak-tight seal and non-sticking operation. To facilitate their use in wet-type automatic sprinkler system risers, Model CV-1FR riser check valves are provided with threaded outlets for pressure gauges and a drain connection. They provide a more compact and economical alternative to an alarm check valve where a water motor alarm is not required.
