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.
