Using worm gear reducer can not only make the butterfly plate with self-locking ability, make the butterfly plate stop at any position, but also improve the operating performance of the valve.
The characteristics of industrial butterfly valve can withstand high temperature, applicable pressure range is also higher, the nominal size of the valve is large, the valve body is made of carbon steel, the sealing ring of the valve plate is made of metal ring instead of rubber ring.
