Pneumatic butterfly valve is a kind of high elastic body, which is made of ordinary materials. The composite ball valve is composed of a metal screw ball valve and high-quality vulcanization wrapped outside.
In terms of corrosion prevention, the rubber ball valve has previously introduced the electroplating metal protection method. The electroplating metal coating anti-corrosion protection method is not only to prevent the ball valve from being eroded, but also to enhance the appearance of the ball valve to a certain extent. It also strengthens the working mechanism of the ball valve on a certain basis, improves the hardness and stability of the ball valve, Therefore, the method of metal protective layer is often used for ball valves on the erosion prevention layer.
The corrosion prevention method of ball valve is to prevent the corrosion of ball valve by keeping the chemical properties of metal zinc in the air unchanged and forming a dense zinc oxide film in humid air. If there are many erosions in the air, the ball valve should be passivated to increase its protection ability and aesthetic level.
Pneumatic butterfly valve has nonlinear elasticity, and its performance curve can be designed into an ideal shape.
