SANJING Wet fire protection system valve is a type of valve used in wet fire protection systems. The wet type fire protection system is a type of fire suppression system that uses water as the primary extinguishing agent. In this wet system, the pipes are filled with water at all times and the sprinkler heads are open. But when a fire is detected, the fire sprinkler in the end of the pipe will break then the alarm valve opens and water flows through the sprinkler heads to extinguish the fire.
Wet fire protection system valves come in a variety of types and sizes, including flanged and grooved end connections. They are made from materials such as cast iron, ductile iron, and bronze to withstand the pressures and corrosive effects of water in the system.
The wet fire protection system valve is a key component of the system. Wet fire protection system valve is responsible for controlling the flow of water in the system and is typically located at the connection between the water supply and the system piping. When the alarm valve opens, water flows through the wet fire protection system valve and into the system piping, where it is distributed to the sprinkler heads.
