The pneumatic ball valve can be closed tightly with the operation of 90 degrees of air rotation and very small rotating torque. The completely equal inner cavity of the valve body provides a straight flow passage with little resistance for the medium. It is generally believed that ball valves are most suitable for direct opening and closing, but recent development has designed ball valves to be used for throttling and flow control. The main characteristics of pneumatic ball valve are its compact structure, easy operation and maintenance, and suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The valve body of pneumatic three piece ball valve (ball valve) can be integral or combined. 　　　　

It is a crucial step for the electric butterfly valve to enter the international market to build a good corporate image and form its own brand products. If we cannot have our own brand products, you will not be recognized by the international market. Owning these independent brand products is also a form of competition in the international market. Only after we have formed these brand products can we compete with others in the international market. For an enterprise, brand is the most important wealth, because these are the signboards representing our entire enterprise.
