ZSFZ200-16WTU-N wet alarm valve is designed for large fire protection systems. DN200 flange connection is suitable for medium and high pressure water supply system, suitable for shopping malls, hospitals and industrial plants. Its core function lies in the intelligent response mechanism under normal high pressure of the pipe network: when the fire triggers the nozzle to rupture, the pressure on the system side drops sharply, the valve disc opens quickly under the pressure difference, drives the hydraulic alarm and pressure switch to act synchronously, and automatically starts the fire pump to continuously supply water.
The valve body can withstand a working pressure of 1.6MPa, and the built-in delay filter filters the pressure fluctuation to prevent false alarms. The product complies with GB5135.2-2003 standard, has passed 3C certification, and supports wet automatic sprinkler fire extinguishing system composed of closed nozzle and water flow indicator. It is widely used in high-rise buildings, underground garages and storage and logistics centers to provide efficient and reliable fire protection.
