The use of worm gear reducer, not only can make the butterfly plate with self-locking ability, so that the butterfly plate stopped in any position, but also improve the operation of the valve performance. Industrial Butterfly Valve features: High temperature resistance, high pressure range, valve nominal diameter, the body is made of carbon steel, valve plate seal ring instead of rubber ring. Large-scale high-temperature Butterfly Valve using steel plate welding manufacturing, mainly used for high-temperature medium smoke duct and gas pipeline.
