BUTTERFLY VALVEThe opening and closing member is a disc-shaped butterfly valve that rotates around its own axis inside the valve body to achieve opening, closing, or regulating. The fully open and fully closed butterfly valve is usually less than 900, and the butterfly valve and stem themselves do not have strong self-locking force. In order to position the butterfly plate, a worm gear reducer should be installed on the stem. By using a worm gear reducer, not only can the butterfly plate have self-locking ability to stop at any position, but it can also improve the operational performance of the valve. The characteristics of industrial butterfly valves are high temperature resistance, high pressure range, large nominal diameter, carbon steel valve body, and metal ring instead of rubber ring for valve plate sealing. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used for flue gas ducts and gas pipelines for high-temperature media.

Advantages of butterfly valves: easy and quick opening and closing, labor-saving, low fluid resistance, and can be operated frequently. Simple structure, small size, and light weight. It can transport mud with minimal liquid accumulation at the pipeline outlet. Under low pressure, good sealing can be achieved. Good regulation performance.
