Wet Alarm Check Valve Introduction:

The ZSFZ series wet alarm valve is a check valve that only allows water flows unidirectionally and
drive the matching part to alarm at prescribed pressure and flow. It constitutes the sprinkler
system with water flow inductor, pressure switch and sprinklers. This valve is divided into two sides
by a valve flap. The above side is connected with system pipeline ant the underside is connected
with water supply. The valve flap will open only when the pressure between the two parts reach a
certain level.

Working Principle:
The alarm valve is always on a set condition the system side is full of pressurized water. The heat
sensitive component on the sprinkler will blast and spray automatically when there is fire
somewhere. Thus the pressure at system side will reduce and then valve flap opens because of
pressure difference. One hand the water supplied to system side, on the other hand a small part of
water flows to delayer and reach water motor alarm finally to make it alarm. The pressure switch
turns pressure signal to electric signal and start fire pump and auxiliary fire-fighting equipments to
put out the fire. Water flow inductor will also work and show the position of fire.
