Product Features and Advantages
Precise Double-eccentric Design: This design enables the butterfly plate to fit the valve seat more effectively during the opening and closing processes, achieving excellent sealing performance. At the same time, it reduces the friction between the butterfly plate and the valve seat, thus extending the service life of the valve.
Production Standards: It is manufactured and inspected in accordance with British Standard 5155 or the standards required by customers, ensuring that the valve meets high-standard quality and reliability requirements in terms of materials, dimensions, and performance, and can be applied in various industrial environments.
Good Fluid Control Performance: The butterfly plate rotates flexibly, allowing for precise control of the fluid flow. It also has a low flow resistance, enabling the fluid to pass through the pipeline smoothly and reducing energy consumption.
Reliable Sealing Performance: High-quality sealing materials and advanced sealing structures are adopted, ensuring good sealing performance under different working pressures and temperatures and effectively preventing the leakage of the medium.
Convenient Installation and Maintenance: The flanged connection method is used, which makes it easy to align and fix with the pipeline during installation, and the operation is simple and quick. In addition, the structural design of the valve is easy to disassemble and repair, reducing maintenance costs and downtime.
