Plug Valve: Principles, Types, Advantages and Applications
14 Aug, 2026
The plug valve is a widely used valve for industrial pipelines. It is primarily used to open and close pipelines and control fluid flow inside pipes. The valve is fitted with a rotatable cylindrical or tapered plug. A through hole runs through the plug, which controls the passage of liquids, gases and slurries. The plug valve boasts a compact structure, low fluid resistance, stable sealing performance and simple routine maintenance. It is extensively adopted across various industrial production lines including petroleum, chemical engineering and natural gas sectors.
Introduction to the Sleeve Plug Valve
09 Aug, 2026
The sleeve plug valve is a commonly used valve in industrial pipelines. This valve is equipped with a replaceable elastic sealing sleeve. The sealing sleeve can wrap around the conical valve core. The valve completes the sealing operation through this structure. By rotating the valve core by 90 degrees, the valve can be controlled to open or close. This valve belongs to a quarter-turn valve. Its operation steps are simple and the sealing effect is stable. It can be normally used in various industrial fluid pipelines such as petroleum, chemical, natural gas, and water treatment.
Plug Valve Composite Self-Sealing Structure: Principle and Engineering Value
06 Aug, 2026
Plug Valves have many practical advantages. They have fast switching speed, low fluid resistance, and do not restrict the flow direction of the medium. These advantages make Plug Valves widely used in important industrial scenarios such as petrochemicals, natural gas transportation, and coal chemical industries.
