How much power does the pneumatic wear-resistant butterfly valve need? The butterfly valve is generally less than 90 ° from full opening to full closing, and the butterfly valve and butterfly stem have no self-locking capacity. In order to position the butterfly plate, a worm gear reducer should be installed on the valve stem. The use of worm gear reducer can not only make the butterfly plate have self-locking ability, make the butterfly plate stop at any position, but also improve the operating performance of the valve.
