FM Approved Alarm Check Valve

Model WAV-1 Alarm Check Valve is a wet pipe sprinkler system water supply check valve that makes possible the installation of sprinkler

systems in buildings not subject to freezing temperatures. It is designed so that water pressure in the piping system will hold back water pressure at the valve until a significant flow of water occurs such as a sprinkler is activated.

The Alarm Check Valve serves as a check valve by trapping pressurized water above the clapper and preventing reverse flow from

sprinkler piping.

The valve is trimmed with a water bypass line. The bypass line allows pressure surges to enter the system and to be trapped above the alarm check valve's clapper without the clapper lifting and causing false alarms.
