1、 Features of pneumatic pneumatic ball valve
1. Simple structure, small size and light weight.
2. The fluid resistance is small, and its resistance coefficient is equal to that of pipe sections with the same length.
3. 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.
4. Tight and reliable, the sealing surface material of pneumatic ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum systems.
5. It is easy to maintain, the pneumatic 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 sealing surface of the pneumatic ball valve.
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 pneumatic ball valve is gas, generally 0.2-0.8MPa, which is relatively safe. If the pneumatic 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 pneumatic ball valves, pneumatic pneumatic ball valves can be configured with large caliber. Manual and turbine rotating pneumatic ball valves are generally below DN300 caliber, and pneumatic pneumatic ball valves can reach DN1200 caliber. As the pneumatic pneumatic ball valve is widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as people's daily life. It has become the work of many experts and scholars to accelerate the research on pneumatic pneumatic ball valves. It is believed that pneumatic pneumatic ball valves will become more satisfactory products in the future.

Applicability of pneumatic butterfly valve connector
The connector is used to connect the hose to the threaded steel pipe or the equipment with external thread of outlet taste
The metal corrugated pipe joint is made of high-quality zinc alloy die-casting and metalworking. The appearance is generally galvanized and hard chrome plated, and the special places are treated according to the requirements. The product has beautiful appearance and tight structure; It has no pores, high strength, and can be connected with hoses, steel pipes and boxes. It has the advantages of good air tightness, shock resistance, corrosion resistance, waterproof, dustproof, etc. The specification size can be arbitrarily changed according to the equipment, box, steel pipe, hose diameter and thread. One end is connected to the hose (steel pipe), and the other end is connected to the switch box, motor, bridge, etc. Please indicate hose specification and thread size when ordering.
The joint can be directly welded:
1) It can be directly welded together without going through a third party to form a permanent joint that cannot be disassembled.
2) It can be completed by any welding process such as fusion welding, pressure welding, brazing, etc.
3) The directly connected welded joints have great application value in the consumption theory and are widely used.
4) The mechanical properties of welded joints are high.
