Product Features

Precise double - eccentric design: This design enables the butterfly plate to fit the valve seat more effectively during the opening and closing process, achieving excellent sealing performance. Meanwhile, it reduces the friction between the butterfly plate and the valve seat, thereby extending the service life of the valve.

Compliance with BS5155: It is strictly manufactured and inspected according to British Standard 5155, ensuring that the valve meets high - level 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 fluid flow. It also has low flow resistance, enabling the fluid to pass through the pipeline smoothly and reducing energy loss.

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 medium leakage.

Convenient installation and maintenance: The flange connection method is used, which facilitates alignment and fixation with the pipeline during installation, and the operation is simple and fast. Moreover, the valve's structural design is easy to disassemble and repair, reducing maintenance costs and downtime.
