Wet Alarm Valve

In China,Fuxeon® specializes in the research and development and production of fire protection products. Our wet alarm valve is essentially a one-way valve that only allows water to flow into the sprinkler system. This system is always on standby, with pressurized water flowing through the pipes. Combined with a flow indicator, signal valve, pressure switch, and sprinkler nozzle, it forms a wet automatic sprinkler system—one of the most widely used fire extinguishing systems worldwide.

Product details:

1.Fuxeon’s wet alarm valves feature a copper valve seat. Long-term exposure to pressurized water makes them particularly resistant to scaling, rust, and corrosion. This copper structure prevents rust from the valve seat, which could lead to poor sealing or seizure, ensuring a more reliable and durable operation.

2.Our factory's valve discs are made of stainless steel, which is much harder than cast iron discs and less susceptible to rust and corrosion in water-based systems.

FAQ

Q1: What main materials make up the wet alarm valve?

The valve body is manufactured from high-strength ductile iron or brass with anti-corrosion coating. Internal seals, diaphragms and gaskets adopt water-resistant, aging-proof rubber materials. Key moving parts, bolts and connectors are made of stainless steel, ensuring long-term pressure resistance, sealing and anti-rust performance.

Q2: What is the working principle of wet alarm valve?

Under normal working conditions, the entire pipeline is always filled with pressurized fire water. When a sprinkler breaks from high temperature, water flows and triggers the wet alarm valve. It will activate the alarm device and send water to the sprinkler network for quick initial fire suppression.

Q3: Is wet alarm valve suitable for long-term water-filled working conditions?

Yes. All wetted parts adopt water corrosion resistant materials. The optimized sealing structure can withstand long-term continuous water pressure without leakage. It runs stably in humid indoor environments with low failure rate and daily maintenance cost.
