Grooved wet alarm check valve is a valve designed for wet fire protection systems and is widely used in fire alarm and fire extinguishing systems. It prevents water backflow through the built-in check valve function, and at the same time, it works with the alarm system to trigger an alarm in time when the water flow is abnormal, ensuring that the system can respond quickly to fire risks.
Grooved wet alarm check valve is a key unit for wet pipe sprinkler systems. Designed with groove ends to ISO 6182, it enables fast and simple grooved coupling installation. The valve maintains tight closure under normal standby pressure. Once fire sprinklers activate, water flow will lift the valve clapper, supplying water to downstream piping and activating alarm accessories for early fire notification. With robust ductile iron construction and premium surface coating, it delivers reliable sealing, low head loss and long‑term stable performance for commercial, industrial and building fire service networks.
