This valve is a rubber-sealed butterfly valve, widely used in water supply and drainage systems, sewage discharge, power generation, oil, chemical, light textile, food, and other industries as an opening or regulating device to control the flow of media. It features a rubber-lined body and a centerline design for the butterfly plate, allowing for bidirectional sealing with reliable performance and a long service life; the butterfly plate is designed reasonably with low flow resistance and minimal pressure loss; its size facilitates installation. Electric butterfly valves use electric actuators for easy operation; pneumatic butterfly valves use pneumatic actuators that provide greater torque and operate smoothly.
