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.

What is the decisive role of stainless steel pneumatic butterfly valve
What is the decisive role of stainless steel pneumatic butterfly valve?
1、 The stainless steel pneumatic butterfly valve can absorb the vibration on the pipeline. The pneumatic butterfly valve can achieve the effect of reducing noise and can not only improve the ability of the system to fatigue and damage. This is the application in the refrigeration unit. The vibration under the operating condition of the compressed mechanical equipment may cause the early failure of the parts on its single thin ring joint. The vibration is transmitted outward along the pipeline, It may cause resonance of the system and destroy other old parts. Not only that, but also the noise caused by vibration will have a great impact on people's physical and mental health. Therefore, it is an important key to control the vibration of the equipment under operating conditions and avoid its outward conduction along the pipeline for the design of tightening machinery.
2、 Compensated displacement
Many mechanical systems and pipeline operations have the problem of displacement compensation, which needs to be handled with flexible pipes. Because they have some problems at different levels, they often bring difficulties to industrial consumption or operation and maintenance. Under such circumstances, it is most appropriate to use pneumatic butterfly valve to compensate for the displacement of pipeline position.
The good comprehensive performance of pneumatic butterfly valve is fully demonstrated here. In the general industrial category, in addition to pressure and temperature, there are also some harsh conditions such as fatigue, corrosion, vibration, pressing, impact, etc
In many complex and changeable pipeline systems, there will be limited space conditions. Fixed pipes cannot be installed, bent, and straightened. The forced device will form fracture and cold correction. Undoubtedly, it is a great hidden danger. It can bring great convenience to the operation of the device and also play a certain role in ensuring the safe operation of the pipeline system. This is the main reason why some pipeline systems must use pneumatic butterfly valves.
A section of bearing smooth oil duct in a certain type of starter has repeatedly broken during practical operation. Since the pneumatic butterfly valve can be bent at will and under the condition of rated bending radius, the internal stress generated by bending is very small.
