ZSFZ type wet alarm valveDetailed product description：

Purpose:
ZSFZ wet alarm valve is used for wet fire extinguishing systems filled with water in pipeline networks. If a fire occurs in the protected area, when one or more nozzles are activated, water begins to flow in the wet system, and this valve opens to allow water to continuously flow towards the wet water area. Simultaneously activate the hydraulic alarm bell, and the pressure switch emits an alarm signal.
Structure: ZSFZ wet alarm valve consists of valve body seat, valve disc and other components. The valve disc closes by its own weight and divides the valve chamber into upper and lower parts. To prevent water pressure fluctuations, a balance structure is designed inside the valve.

Features:
1. When the system side releases water at a flow rate of ≤ 15L/min under a pressure of 0.14MPa, no alarm signal is issued.
2. When the pressure is between 0.14-1.2MPa and the flow rate is within 6m/s, it can function normally without adjustment.
3. When the water flow on the system side stops, the hydraulic alarm bell stops working.
4. No manual reset is required, and the alarm can be triggered accordingly.
5. When the water pressure is 0.14MPa, the alarm outlet pressure is ≥ 0.05MPa.
6. Each alarm valve device should not control more than 800 nozzles.
