Plug Valve
Item Name Code (INC) 05490
 |
A valve designed to control the flow of a fluid by the rotation of a ported plug or plug sector within a suitable ported seat. The plug requires lubrication for ease of operation or contains a bonded composition seal(s). See also VALVE, SEATLESS and COCK, PLUG.
Additional Information for Plug Valve
A plug valve is a type of valve that is used to control the flow of fluid through a pipe or pipeline. It consists of a cylindrical or conical plug that can be rotated within the valve body to open or close the flow passage.
The plug valve has a hollow or solid plug that is connected to a stem. When the stem is turned, the plug rotates within the valve body, either allowing or blocking the flow of fluid. The plug can be designed with a through-hole, known as a port, which allows the fluid to flow through when the valve is open. Alternatively, the plug can be designed to completely block the flow when the valve is closed.
Plug valves are commonly used in various industries, including oil and gas, chemical, and water treatment. They are known for their simple design, reliable operation, and ability to handle a wide range of fluids and pressures. Plug valves can be used for both on/off applications and for throttling or regulating the flow of fluid.
There are different types of plug valves, including lubricated plug valves, non-lubricated plug valves, and sleeved plug valves. Lubricated plug valves have a lubricant injected between the plug and the valve body to reduce friction and ensure smooth operation. Non-lubricated plug valves are designed to operate without any external lubrication. Sleeved plug valves have a flexible sleeve or lining that provides a tight seal and protects the plug from corrosion or erosion.
Overall, plug valves are versatile and reliable valves that are widely used in various industries for controlling the flow of fluids.
