The Alarm Check Valve are designed expressly for use in wet pipe systems. The valve will open and allow pressurization of the alarm chamber upon the operation of one or more automatic fire sprinklers.

The pressurization of the alarm chamber causes the alarm to sound mechanically through the use of a water motor alarm or through the use of a pressure switch, electrically connected to audible or visual signaling devices.

1.3”  Flange/Groove Alarm Check Valve

2.4”  Flange/Groove Alarm Check Valve
