2、 Fixed Ball Pneumatic Ball Valve The ball of the pneumatic ball valve is fixed and does not move under pressure. All fixed ball valves are equipped with floating valve seats. After being pressured by the medium, the valve seats will move, making the seal ring tightly press on the ball to ensure sealing. Generally, bearings are installed on the upper and lower shafts of the ball, and the operating torque is small. It is suitable for valves with high pressure and large diameter. In order to reduce the operating torque of pneumatic ball valves and increase the reliability of sealing, oil sealed ball valves have been presented in recent years, which not only inject special lubricating oil between the sealing surfaces to form an oil film, which not only enhances the sealing performance, but also reduces the operating torque, and is more suitable for high pressure and large caliber ball valves. How many types of pneumatic ball valves can be divided according to the structure?

At present, there are many uses of pneumatic switch ball valves, which are used in many different pipelines transporting different substances. Therefore, we should particularly understand the characteristics of this product during the use of this equipment, and then get more practical help from the use process, For example, this device has many different types, and different types of products have their own characteristics. Therefore, people should make a good understanding of the products they use according to their actual use environment.
