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.

Lubricated Sealing: The Core Advantage and Adaptability to Working Conditions of Ball Valves and Butterfly Valves
01 Aug, 2026
Ball valves and butterfly valves have a wide range of applications and occupy a significant share of the industrial valve market. However, in special scenarios such as gas pipelines, oil and gas transportation pipelines, and municipal water supply systems, the rotary plug valve still has an indispensable use value. The main advantage of the rotary plug valve is not simply the 90-degree rotation and operation, but its exclusive dynamic lubricated sealing structure. This core technical feature has earned wide recognition from engineering contractors and overseas purchasing customers, and also distinguishes the rotary plug valve from other types of valves.
