A Plug Valve are used to control and regulate flow control of a liquid or gas within a high-pressure system. As well as basic control of flow via throttling, plug valves can be used to divert flow or combine flow.
Plug valves are a mechanically simple valve that utilizes a plug which rotates inside the valve body to control flow through the valve. The plugs within the valve contain one or more hollow channel that cuts sideways through the plug, this allows fluid or gas to flow through the plug when the valve is open. This simple mechanism and ease of operation mean that plug valves are often economical.
Plug valves shut-off and on valves in areas with corrosive & hazardous liquids and gas.
