Butterfly valve is a kind of valve that the closing part (disc or disc) is a disk and rotates around the valve shaft to open and close. It is mainly used for cutting off and throttling on the pipe.The opening and closing part of butterfly valve is a disc-shaped disc rotating around its own axis in the valve body, thus achieving the purpose of opening and closing or adjusting.Butterfly valve fully open to fully close is usually less than 90°, butterfly valve and the butterfly stem itself has no self-locking ability, in order to butterfly plate positioning, to install worm gear reducer on the valve stem.Using worm gear reducer, not only can make the disc has self-locking ability, so that the disc stops at any position, but also can improve the operating performance of the valve.
Flowx double offset butterfly valve(high performance butterfly valve) is a new type of butterfly valve designed based on the advantages of absorbing several different structural butterfly valves. The valve plate sealing surface of this butterfly valve is a ball arc body, and the sealing machanism achieves a true dynamic seal through the systerm pressure, so it has excellent cutting performance and durability performance. Its small size, light weight, a wide range of manufacturing, easy maintenance.
