Efficient and convenient operation: Just rotate 90° to achieve quick opening and closing. The operation is simple and intuitive, with fast response and suitable for scenarios requiring rapid control of medium flow.
Compact and energy-efficient structure: Small in size, light in weight, occupying less space, and easy to install; when fully open, the thickness of the butterfly plate is the only resistance for the medium to flow through, resulting in a small pressure drop, which can reduce energy loss in the pipeline system and achieve energy-saving effects.
Excellent sealing performance and long service life: Adopting a double eccentric structure + inclined conical elliptical seal (or three-way eccentric wedge design), it solves the problem of friction and wear on the sealing surface during the opening and closing of traditional butterfly valves, achieving immediate separation upon opening and immediate sealing upon closing, effectively extending service life, while maintaining good sealing performance and reducing medium leakage and waste.
Strong adaptability and wide application range: Supports various installation methods such as flange and clamp, and can be replaced with different material valve bodies (gray cast iron, stainless steel, aluminum alloy, etc.) to adapt to corrosive gases, liquids, and other media; it can also be adapted to pneumatic/electric actuators to meet the requirements of remote control and program control for automation.
Low maintenance cost: Simple structure, few parts, convenient disassembly and maintenance, which can shorten maintenance time and reduce equipment operation and maintenance costs.
