3、 Features of electric on-off butterfly valve The butterfly valve also has its unique features and advantages. The start and close of the butterfly valve are very simple and fast, and the structure is simple. It can even transport mud, a special fluid. Under low pressure, the sealing performance of the butterfly valve is very good, also because of these reasons, The butterfly valve has good regulating capacity. In addition, the butterfly valve has one of the biggest advantages over other types of valves. The butterfly valve has a two-way sealing property. No matter what the direction of the fluid, it can have a sealing blocking effect. That is to say, the butterfly valve is not affected by the direction of the fluid, which really reduces a lot of troubles during installation. 　　

It is required to carry out all-round anti-corrosion technology inside the valve body and each part of the valve plate of the pneumatic valve. On one level, it is required to immerse in water without rust, and there is no electrochemical corrosion in the two metals; The smoothness of the surface on the other layer will reduce the resistance of water.
