Products Description
Eccentric Ball Valve is an industrial valve used in sectors such as petroleum, chemical, and metallurgical industries. As a type of ball valve, it primarily controls the cut-off, distribution, and flow direction of media by rotating an eccentric ball. Its core components include the ball, seat, and stem, enabling on/off operation with a 90° rotation of the valve core. It is suitable for a wide range of operating conditions, from high vacuum to high pressure.
The valve employs an eccentric structure and wedge sealing technology, ensuring frictionless operation during opening and closing. This design reduces seal wear, extends service life, and features a self-cleaning function to flush out media residues. The seat is designed for adaptive adjustment, using a spring mechanism to automatically center the sealing surface, making it suitable for complex conditions involving particulate-laden or viscous fluids.
With a single-seat design and top-entry structure, the valve prevents abnormal pressure buildup in the media and allows for online maintenance. It is typically installed horizontally, with port sizes ranging from millimeters to meters, making it ideal for industrial applications requiring precise flow control.

Construction Materials
Advantages:
Low fluid resistance, with a resistance coefficient equal to that of a pipe section of the same length.
Simple structure, compact size, and lightweight.
Tight and reliable: The sealing surfaces of ball valves are commonly made of plastic, ensuring excellent sealing performance. They are also widely used in vacuum systems.
Easy operation: Quick opening and closing-only a 90° rotation is required to fully open or close the valve, facilitating remote control.
Easy maintenance: The simple structure of ball valves allows for convenient disassembly and replacement of the movable sealing rings.
Seal protection: When fully open or closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve seals by the fluid.
Wide range of applications: Suitable for port sizes from a few millimeters to several meters and for use in high-vacuum to high-pressure systems.
