A fire alarm check valve is a component in wet pipe fire sprinkler systems that controls water flow, prevents backflow, and activates alarms when a fire is detected. It remains closed and holds back water pressure until a sprinkler activates, at which point a significant flow of water opens the valve and triggers an alarm, such as a water gong or pressure-activated switch. 

A deluge valve is a quick-opening, diaphragm-operated valve used in fire protection systems to rapidly flood a hazard area with water or foam when a fire is detected. It is designed for high-risk environments like refineries, chemical facilities, and aircraft hangars, where immediate suppression is critical. Activation can be triggered by heat, smoke, or manual release systems. 

The Inspectors Test Valve is designed to perform the NFPA 25 required sprinkler system's alarm or water flow device.

An air release valve is a mechanical device designed to automatically expel trapped air from pressurized systems. This is crucial for maintaining system integrity, preventing damage, and ensuring efficient operation in various industries, including water and irrigation systems. Trapped air can lead to pump failures, corrosion, flow issues, and even water hammer or pressure surges.
