Fire hydrant valve is a device that controls the water flow of a fire hydrant

A fire hydrant valve, also known as a fire service valve, is a device used to control the flow of water from a fire hydrant in the event of a fire. Fire hydrant valves are typically installed on the side of the hydrant and are used by firefighters to connect hoses to the water supply.

The valve is typically made of brass or another durable metal and is designed to withstand high water pressure and exposure to the elements. It typically has a hand-operated wheel or lever that controls the opening and closing of the valve. When the valve is opened, water flows from the hydrant through the valve and into the connected hoses.

Fire hydrant valves can have different connection types, such as threaded or storz, to ensure compatibility with different types of fire hoses. They may also include additional features, such as a pressure gauge, to allow firefighters to monitor the water pressure and flow rate.

Fire hydrant valves are an important part of a fire protection system and are installed in locations such as streets, parking lots, and industrial complexes. It is essential to keep these valves accessible and properly maintained to ensure that they function properly when needed.
