Characteristics: It has anti-reset automatic locking function: the valve is match a anti-reset
controller, when the solenoid valve or manual ball valve is opened in
case of fire, if the solenoid valve or manual ball valve is closed because
of the malfunction, because the anti-reset controller is closing, so the
pressure in the main valve control chamber can’t rise, so the deluge valve
has been always turned on.
 The reset operation is simple
 Long life: the diaphragm of the valve uses high intensity nylon rubber, there would not be fatigue damage even
if the diaphragm in tens of millions of times action. The diaphragm can work more than 100,000 hours, to ensure
the valve has a long life.
 High valve bearing pressure and high reliable of the large-diameter deluge alarm valve.

Profile: There are three ways to open the deluge alarm valve: automatic solenoidvalve open, artificial manual open close ball valve and away from the fire
to open the remote ball valve. In case of fire, they can ensure the deluge
alarm valve opens.

The main technical parameters:

Working pressure: 1.6MPa, 2.5MPa
Lowest working pressure: 0.05MPa
Suitable medium: Clean water, polluted water
Suitable temperature: 0~80℃
Hydraulic friction loss: On national standard GB5135.5-2003 flow condition, the hydraulic friction loss is
not more than 0.07MPa
