Wet Pipe System Fire Alarm Check Valve
* The alarm check valve is a water flow alarm device designed for vertical installation in the main supply to a wet pipe sprinkler system. When a flow of water from the system equals or exceeds that of a single sprinkler, the valve is to actuate a fire alarm.
* The wet fire alarm check valve is designed to allow water to flow into the fire sprinkler system when a pressure drop is detected. It contains a check valve mechanism that opens and allows water to enter the system when the in the fire sprinkler system drops below a certain set point. This typically occurs when a fire occurs and activates the sprinkler heads.

Alarm valves are critical components in fire protection systems, designed to detect and respond to fire emergencies swiftly and effectively. As a vital part of fire suppression systems, alarm valves play a crucial role in triggering alerts and activating sprinkler systems in the event of a fire. These valves are engineered with precision and reliability to ensure that once a fire is detected, the alarm valve will promptly signal the need for action, helping to mitigate the spread of flames and protect lives and property.
