Grooved wet alarm valve (ZSFZ8X3-98C) DN80-DN200

Product overview:

Wet alarm valve is a one-way valve that only allows water to be injected into the sprinkler system in one direction and alarms at a specified flow rate. The wet automatic sprinkler fire extinguishing system composed of it and other components such as pressure switches, water flow indicators, sprinklers, etc. is a widely used fixed fire extinguishing system. Usually installed in production places with fire risk, such as warehouses, hotels, shopping malls, hospitals, theaters, office buildings, especially suitable for high-rise buildings and underground projects.

Product advantages:

① Prevent false alarms: The compensation structure within the valve disc prevents false alarms due to leakage in the pipe network system or fluctuations in water source pressure.

②Self-test function: It has its own test system, which can test whether the valve is in normal response state by opening the manual ball valve in the absence of fire.

③Small flow resistance and low energy consumption: The valve body has a full flow design structure, which reduces the flow resistance loss and saves energy.

④Long life: Internal metal parts are made of corrosion-resistant copper alloy and stainless steel, with long service life.

⑤Complete certifications: The products have passed authoritative fire protection certifications such as FM/UL/VDS and 3C in the United States.
