3、 Working principle of connection between ball valve and pneumatic actuator:
1. The pneumatic ball valve can be closed tightly only by the operation of 90 degrees of air rotation and a 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.
2. The valve can be unblocked or blocked by rotating the valve element. The pneumatic ball valve is light to open and close, small in size, can be made into a large caliber, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often closed, not easy to be eroded by media, so it is widely used in various industries.
3. Pneumatic ball valve and plug valve belong to the same type of valve, only its closing part is a ball, and the ball rotates around the center line of the valve body to open and close a valve.
4. Pneumatic ball valves are mainly used in pipelines to cut off quickly, distribute and change the flow direction of media.

The pneumatic butterfly valve industry has become an important topic in the operation of the industry. The pneumatic butterfly valve industry has become an important topic in the operation of the industry
Most of the small and medium-sized pneumatic butterfly valve enterprises are at the low end of the traditional industrial value chain, with weak technological innovation ability, extensive consumption and operation, low level of deployment, shortage of professional talents, lack of independent knowledge, property rights and brands. They mainly rely on "low cost, low price and low profit" to participate in the competition, and it is difficult to digest the rising factors of operating costs in a timely manner, Conform to the ideal request of changing the mode of development and adjusting and optimizing the economic structure.
With the increasing global competition, in order to improve competitiveness, the pneumatic butterfly valve industry has become an important topic in the operation of the industry. As a pneumatic butterfly valve factory, it is necessary to understand the needs of the market and customers, and then develop processing plans based on their needs, personalized needs. In the world, quality is the foundation. On the other hand, The sales interpersonal relationship of pneumatic butterfly valve is one of the three very important elements. In this element, quality is the foundation. Good interpersonal relationship is more conducive to the opening of sales channels, but quality is the guarantee of long-term cooperation. Do a good job of publicity and procurement. On the basis of excellent products, do a good job of publicity. Manufacturers should be good at purchasing and promoting themselves. Through publicity, the company's brand advantages, quality advantages, capital advantages and other advantages in the pneumatic butterfly valve industry are displayed, so that more customers and peers can understand us and know us. In recent years, with the continuous development of economy, China's stainless steel pneumatic butterfly valve processing industry has gradually become the main force of the world's pneumatic butterfly valve tool industry.
