Pneumatic proportional control valve has the advantages of good stability, strong versatility and easy maintenance. The single seal type is suitable for occasions with strict leakage requirements and unclean media with pressure difference. After improvement, it can be used as a stop valve. The double seal type is suitable for clean media with loose leakage requirements and large pressure difference. The small hole throttling type can be used for low-noise valves.
1. The balanced valve core is adopted, the unbalanced force is large, the allowable pressure difference is large, and the operation is stable.
2. The valve core guide surface is large, which can improve the vibration caused by vortex and impact.
3. The noise reduction is about 10dB compared with ordinary single and double seat control valves.
4. The structure is simple and easy to install and maintain.
