Cast Iron Plug Valve

A cast iron plug valve is a type of valve that is used to control the flow of liquids and gases. It is a quarter-turn valve, meaning it is opened and closed by rotating the valve stem a quarter turn. The plug valve is designed with a cylindrical or conical plug that fits into a matching seat in the valve body. The plug has one or more holes or passages that allow the flow of the fluid when the valve is open. When the valve is closed, the plug seals against the seat, preventing the flow of the fluid. Cast iron plug valves are used in a variety of applications, including water, oil, and gas pipelines.
