Control Signal Valve (Wet Alarm Valve)

The Control Signal Valve is one of the main devices used in wet automatic sprinkler fire suppression systems, managing water flow and ensuring the activation of the fire signal. The valve is installed between the water supply line and the sprinkler pipe network, maintaining water under pressure in normal operating conditions. When a fire occurs and the sprinkler head opens, the resulting water flow allows the valve to open and the water to be delivered to the protected area. At the same time, the fire alarm is activated via a hydraulic signal device or pressure switch.

Control Signal Valves are available in nominal diameter ranges of DN50–DN300 and are used according to the requirements of various sizes of fire protection systems. The valve body is made of ductile iron material with high mechanical strength and pressure resistance. Internal components and sealing elements are designed for reliable operation and long-term performance.

Products are certified with UL and FM certifications, confirming compliance with relevant fire safety requirements. Depending on the model, the valve can be equipped with additional components such as hydraulic signal devices, delay chambers, pressure gauges, and pressure switches.

Control Signal Valves are used in commercial buildings, industrial facilities, warehouses, logistics centers, and other objects where sprinkler fire suppression systems are applied.
