What is an Industrial Plug Valve?

A plug valve is a valve that controls the flow of fluid by rotating a cylindrical or conical cock with a through hole. The plug valve is simple in design and flexible in operation, and is suitable for frequently opened and closed applications. Similar to a ball valve, a plug valve opens or closes the valve by turning it 90 degrees, but it is more compact. Plug valves are widely used in the oil, gas and chemical industries, especially where quick opening and closing and leakage prevention are required. Plug valves can be operated by handle or actuator for easy and reliable operation and are ideal for high temperature, high pressure and corrosive media pipelines.

Characteristics of Valve Use

Compact design

The plug valve is compact and easy to operate, suitable for industrial environments requiring frequent opening and closing, such as oil and gas pipelines and chemical plants.
Quick opening and closing

The plug valve can be quickly opened and closed by rotating 90 degrees, which is especially suitable for applications requiring fast response.
Two-way flow

The plug valve allows fluid to flow from any direction, with good two-way sealing performance, suitable for multi-direction flow pipeline system.
Easy maintenance

The design of the plug valve is simple, easy maintenance, and the replacement of seals and plugs is also more convenient, reducing the overall maintenance cost.

About The Key Parts of The Plug Valve

01

Valve Body

The valve body of a plug valve is usually cast in one piece, with a compact design that can withstand high pressure and high temperature conditions. The inside of the valve body is smooth, reducing friction and resistance when the fluid passes through.
02

Plug

The plug is a key component for controlling the flow of fluid. It is usually conical or cylindrical with a channel inside. The opening and closing control of the fluid can be quickly achieved by rotating the plug.
03

Valve Seat

The valve seat contacts the plug to form a seal. The valve seat material is usually metal or elastic material, which can provide good sealing performance and prevent fluid leakage.
04

Seal Ring

The seal ring is located between the plug and the valve body to ensure that the fluid does not leak when the plug rotates. The seal ring is usually made of elastic material with good wear and corrosion resistance.
05

Operation

The operation of the plug valve can be operated by a manual lever or automatically controlled by an electric or pneumatic actuator. Manual operation is suitable for simple working conditions, while automatic operation is suitable for complex working conditions and remote operation.
