2、 Structure characteristics of internal thread pneumatic ball valve
1. The fluid resistance is small, and its resistance coefficient is equal to that of pipe sections with the same length.
2. Simple structure, small volume and light weight.
3. Tight and reliable. At present, plastic is widely used as the sealing surface material of pneumatic ball valve with good sealing performance, and it has also been widely used in vacuum systems.
4. It is easy to operate and can be opened and closed quickly. It only needs to rotate 90 ° from full opening to full closing to facilitate remote control.
5. Easy maintenance, simple structure of pneumatic ball valve, generally movable sealing ring, easy removal and replacement.
6. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the sealing surface of the pneumatic ball valve.
7. It has a wide range of applications. The internal thread pneumatic ball valve can be used from a few millimeters to several meters, from high vacuum to high pressure.

Influence of quality of stainless steel pneumatic butterfly valve
With the rapid development of modern industry and the mutual penetration of science and technology, the market of stainless steel hose is in a state of disorder. Because in the hose industry, a large number of low-quality products emerge in endlessly, and these products have not entered the market without national inspection
After entering the market, due to the low price, it was welcomed by some customers who like small businesses. However, this has a certain impact on our hose market. Many of them bought these low-quality products because of the low price, so they can not be used in a short time
Therefore, the quality of stainless steel pneumatic butterfly valve is the decisive factor to decide the mainstream of the hose market. Poor stainless steel hose will have a negative impact on the market. In order to adhere to and stabilize the balance of the market, our company has decided to start from myself, first from myself, and improve the quality of products
If you want to gain more market share and more development space, you must win from the consumption process. Enterprises that consume low-quality corrugated pneumatic butterfly valve products will create their own graves in the future market competition. The development of such enterprises will not last too long because they sell their reputation and their quality
