The influence of the flow of media on the pneumatic control valve

Due to the change in the direction of the flow of media, there are four kinds of effects on the pneumatic control valve

1. The valve pressure before and after P1, P2 exchange, unbalanced direction of action of the force Ft or size change;

2. The flow direction of the spool is changed by the media, so that the manifold is changed, and the resistance of the fluid is different;

3. To change the media flow, so that the valve seat to produce erosion and cavitation changes in the situation, thus changing the life of the valve

4. Influence on the working performance of pneumatic control valve
