Dry Alarm Valve

The durable Dry Alarm Valve supplied by Fuxeon® is used as a water supply control valve in dry sprinkler systems. Under normal conditions, the pipeline system is pressurized with gas (which also monitors the pipeline's airtightness), keeping the valve in a closed position. When a fire occurs, the valve activates, allowing water to enter the pipeline system.

Technical parameters：

Product Features:

The pipeline side of the sprinkler head is filled with gas, not water;

It can work in extreme weather to prevent water from freezing or evaporating in the pipes.

How does it work?

When there is a fire, the fire sprinkler works, the air pressure in the pipe network begins to drop, when it drops to a certain value, the valve of the dry alarm valve opens, and the water enters the pipe network system and sprays out from the fire sprinkler, performing the fire extinguishing function and triggering the alarm at the same time. After extinguishing the fire, the valve needs to be manually closed and re-inflated.

Where can it be applied?

Our dry alarm valves can be used in cold storage below 4°C, and can also be used in flour mills, boiler rooms, and drying workshops, which can solve fire problems in special environments.

FAQ

Q1: What is the working feature of dry alarm valve?

Under normal conditions, the pipeline is filled with compressed air or nitrogen, and no water inside. When a fire breaks out and the sprinkler activates, air pressure drops, the dry alarm valve opens automatically, and water enters the pipe network for fire spraying. It effectively avoids pipe freezing and bursting in cold climates.

Q2: Can dry alarm valve work reliably in low temperature and harsh conditions?

Yes. Adopting special cold-resistant sealing materials and anti-freeze structural design, it can stably operate in long-term low-temperature and frost environments. The metal body features rust-proof and anti-oxidation performance, adapting to humid, cold and poorly insulated industrial spaces.

Q3: What are the usage limitations and matching requirements?

It matches air pressure supply equipment and dry pipe fire systems, only for clean fire water. Not suitable for strong corrosive media, high-temperature workshops or severe vibration occasions. Regular air pressure inspection and maintenance of sealing parts are required to ensure sensitive alarm and rapid water supply.
