Grooved End Connection Butterfly Valve
Butterfly valves are usually less than 90 degrees open to close. Butterfly valves and butterfly rods have no self-locking ability. In order to locate the butterfly plate, worm gear reducer should be installed on the valve stem. Using worm gear reducer can not only make butterfly valve plate have self-locking ability, make butterfly valve plate stop at any position, but also improve the operation performance of the valve. Industrial butterfly valves are characterized by high temperature resistance, high pressure range, large nominal diameter, carbon steel body and metal ring instead of rubber ring. Large high temperature butterfly valve is welded by steel plate, mainly used for flue gas duct and gas pipeline of high temperature medium.
