Sleeve Plug Valve

Sleeve plug valve is a plug valve with a jacket structure. The working principle is that the plug rotates 90° around the axis to open and close, which is different from the traditional ball valve or gate valve. Its uniqueness lies in its distinctive sleeve and ferrule design, which forms a unique sealing mechanism. The valve relies on the precise fit between the sleeve and the valve body as well as the sealing effect of the ferrule to ensure excellent sealing performance. Even under high-pressure or high-temperature working conditions, it can maintain a reliable sealing effect and effectively prevent medium leakage. The advantages lie in anti-crystallization and anti-solidification, reducing the increase of medium viscosity, wide application range and convenient maintenance. It is applied in industries such as chemical engineering, petroleum, and food, and is suitable for pipeline control of media that are prone to solidification and high viscosity, such as asphalt, resin, and high-viscosity oil products.
