When in use, the height, bearing capacity and stiffness of the ball valve can be widely selected to obtain its soft ball valve performance.
Height of ball valve: height control valve can be used to properly control the height of pneumatic ball valve according to the use requirements, and maintain a certain height when the spring load changes.
Bearing capacity: for pneumatic ball valves of the same size, different bearing capacity can be obtained by changing the internal pressure, which is roughly proportional to the internal pressure. This enables the unified pneumatic ball valve to adapt to various load requirements.
Ball valve stiffness: when designing the stiffness of pneumatic ball valve, it can be selected by changing the internal pressure of the ball valve. The stiffness is roughly proportional to the internal pressure. Therefore, the stiffness can be selected very low as required. For an automobile air valve with a given size, the stiffness is variable, and it changes with the change of load, so the natural vibration frequency is almost constant under any load, Therefore, it can make the supported system have almost constant function.
1. The natural vibration frequency of the pneumatic ball valve is relatively low, but the natural vibration frequency of the pneumatic ball valve device is reduced to 0.5~3Hz. Under the action of any load, the pneumatic ball valve can maintain a low and nearly equal vibration frequency.

2. It can isolate high-frequency vibration and noise. The pneumatic ball valve is composed of air and has small internal friction. The inherent vibration of the ball valve itself will not affect the ability to isolate high-frequency vibration. In addition, the pneumatic ball valve has no metal to metal contact, so its noise isolation and anti noise effect are very good.
