As early as the 1950s, the spherical valve came out. After decades of development, this kind of spherical valve has been widely used in various fields. The pneumatic high-pressure ball valve is a more advanced new ball valve, which is realized through the continuous improvement and development of the ball valve. This is entirely due to the development of mechanical automation, which greatly improves the accuracy and fineness of materials and ingredients. The most popular is the plastic ball valve, which is completely corrosion resistant, important and light, and has a very low manufacturing cost. 　　　　

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.
