Product Description

Product Description

 

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.
