Deluge Valve (Control Signal Valve)

The Deluge Valve is a key control component used in automatic fire suppression systems, ensuring the rapid delivery of water or other suitable fire extinguishing agents to the protected area during a fire. These valves are primarily applied in deluge systems equipped with open-type sprinkler heads or water spray nozzles. In normal operating mode, the valve remains closed. When a fire is detected, the detection system activates the valve through an electric solenoid or hydraulic-pneumatic control mechanism, allowing water to enter all open nozzles simultaneously.

Deluge Valves are available in a nominal diameter range of DN50–DN300 and are used in industrial, oil and gas, energy, warehouse, and other high fire-risk facilities. The valve body is made of spheroidal cast iron material, which has high mechanical strength and pressure resistance. Internal components and sealing elements are designed for reliable operation and long-term service.

The products are certified with UL and FM certifications, confirming compliance with relevant fire safety requirements. Depending on the system configuration, the valve can be equipped with solenoid valves, pressure switches, manometers, hydraulic or pneumatic control devices.

Deluge Valves are designed to prevent the rapid spread of fire hazards and provide simultaneous water protection over large areas.
