PRODUCT FEATURES
Simple structure, small external dimensions, and short structural length;
The opening and closing torque is relatively small. Due to the fact that the butterfly plates on both sides of the shaft are subjected to the same medium effect, the direction of torque generation is opposite, making opening and closing more effortless;
Good sealing can be achieved under low pressure;
Good regulation performance;
The butterfly plate adopts a frame structure, with high strength and a large overcurrent area;
This valve has a bidirectional sealing function and is not controlled by the flow direction of the medium or the spatial position during installation. It can be installed in any direction.
