The butterfly valves manufactured by our company can be categorized into handle-operated, worm gear-driven, pneumatic, and electric butterfly valves based on different actuation methods.

Handle-operated butterfly valves are equipped with a handle for manual operation to open or close the valve. They are suitable for pipelines with diameters up to DN200 (larger diameters would require excessive force for manual operation). Our handle-operated butterfly valves feature a compact and lightweight design, making them easy to disassemble and maintain. They can be installed in any orientation and offer a simple yet robust structure with minimal operating torque. The valve can be fully opened with a 90-degree rotation and provides excellent control performance.

Worm gear-driven butterfly valves are fitted with a worm gear mechanism that facilitates smooth and precise control of the valve's opening and closing as well as flow regulation. These valves are ideal for large-diameter pipelines. Our worm gear-driven butterfly valves are constructed using corrosion-resistant synthetic rubber, including EPDM and fluororubber, ensuring outstanding resistance to corrosive media such as acids and alkalis. This construction also guarantees superior sealing performance. Installation is straightforward, and the valves are user-friendly.
