Alarm Check Valve

 

Model WAV-1 Alarm Check Valve Alarm check valve is mainly used in wet pipe fire protection system, which prevents the reverse flow and controls water pressure. It automatically actuates alarm when water flows into the system upon fire sprinkler operation. 

 

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.
