Produktbeschreibung:

The wet alarm valve is a one-way valve that only allows water to flow into the sprinkler system in one direction and alarms at a specified flow rate. The wet alarm valve usually equals the water pressure before and after the valve disc (the water passes through the water pressure balance hole in the guide pipe to keep the water pressure balance before and after the valve disc).
ZSFZ-E Wet alarm valve is the key component of automatic sprinkler system. It consist of wet alarm valves, retard, water alarm, and other components (such as pressure switches, flow meters, closed head etc.). The system usually in standby state, the pressure pipe filled with water.
