Application

Butterfly valve refers to a closing piece (valve or disc) is a disc, a valve that rotates around the valve shaft to open and close, mainly cutting and throttling on the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting. The butterfly valve is normally less than 90° from full opening to full closing. The butterfly valve and the butterfly rod have no self-locking capability. For the positioning of the butterfly plate, a worm gear reducer is added to the valve stem. The use of a worm gear reducer not only enables the disc to have a self-locking capability, but also stops the disc at any position and improves the valve's operating performance. Features of industrial special butterfly valve: It can withstand high temperature, and the applicable pressure range is also high. The valve has a large nominal diameter. The valve body is made of carbon steel. The sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high temperature butterfly valves are manufactured by steel plate welding and are mainly used for flue ducts and gas pipes of high temperature media.

Strength

3. Can transport mud, the least amount of liquid accumulated in the pipe mouth.
4. Under low pressure, can achieve a good seal.
5. The adjustment performance is good.
6. The valve seat channel has a large effective flow area and a small fluid resistance when fully opened.
