Wet Alarm Valve

The Wet Alarm Valve is a double-seated clapper check valve designed for wet pipe fire sprinkler systems. It automatically activates both mechanical and electrical alarms when water flows through the sprinkler system during a fire, while preventing false alarms caused by pressure fluctuations. Ideal for commercial buildings, industrial facilities, warehouses, and fire protection systems.
