The Wet Alarm Valve is an automatic device installed in wet-pipe fire sprinkler systems.
When a sprinkler operates due to heat, water flows into the system piping and through the valve.
The valve then activates connected alarm devices such as a water motor alarm and/or pressure switch, providing both audible and electrical fire alarm signals.
It includes a retard chamber to prevent false alarms caused by pressure surges and ensures accurate alarm activation during real fire flow conditions.
The valve body is corrosion resistant and designed for long-term stability and reliability.
