Description
An Alarm Check Valve is a critical component of wet pipe fire sprinkler systems, designed to allow water to flow into the sprinkler system while preventing reverse flow. When a sprinkler head operates due to fire, the movement of water through the valve activates a mechanical or electrical alarm, providing an immediate indication of fire or system operation.
The valve integrates a check valve mechanism with an alarm outlet, ensuring reliable fire detection and system integrity. Alarm Check Valves are manufactured from high-quality Ductile Iron or Cast Iron with corrosion-resistant coatings to ensure long service life and dependable performance. They are widely used in commercial buildings, industrial facilities, warehouses, and fire protection installations in compliance with fire safety standards.
