Pneumatic ball valves are mainly used in pipelines to cut off quickly, distribute and change the flow direction of media. Pneumatic ball valve is a new type of valve, which has the following advantages:
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 size and light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, with good sealing performance. 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, which is convenient for remote control.
5. It is easy to maintain, the pneumatic ball valve is simple in structure, the sealing ring is generally movable, and it is easy to remove and replace.
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 valve sealing surface.
7. It has a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.
8. Because the power source of pneumatic ball valve is gas, which is generally 0, 2-0, and 8MPa, it is relatively safe. If the pneumatic ball valve leaks, compared with the hydraulic and electric valves, the gas can be discharged directly, which does not pollute the environment and has high safety.
9. Compared with manual and turbine rotating ball valves, pneumatic ball valves can be configured with large caliber (manual and turbine rotating ball valves are generally under DN300 caliber, and pneumatic ball valves can reach DN1200 caliber.)

What are the characteristics of pneumatic butterfly valve
It is used for the sensor circuit maintenance of fine optical ruler and industrial sensor circuit maintenance. It has good flexibility, corrosion resistance, high temperature resistance, wear resistance and tensile resistance. What are its characteristics and characteristics? Next, I will analyze it for you.
1. The pneumatic butterfly valve is made of 1Cr18Ni9Ti stainless steel, which has strong corrosion resistance.
2. The hose body is a thin-walled stainless steel tube formed by hydraulic pressure, which has strong flexibility, flexibility, bending and vibration resistance. The woven mesh sleeve has enhanced maintenance, making it more capable of bearing pressure.
3. The connection of both ends of the hose can also be made into other connection modes except for the screw thread and flange specifications, which is convenient for connection and application. 4. Pneumatic butterfly valves are not only suitable for matching with rotary joints, but also widely used for soft connection of various fluid media.
