Porous control valve

The multi hole low noise pneumatic control valve adopts sleeve guide and pressure balance valve core. It is a high performance control valve with good dynamic stability and suitable for harsh working conditions. Because the working condition pressure difference is big, the medium flow rate is fast, the valve internals will produce serious erosion damage and noise at the same time. Therefore, we changed the window type standard sleeve into a porous sleeve. For the general flow direction of liquid is from high to low of the valve, the medium is collided in the sleeve by porous throttling, and the internal energy consumption can reduce the flow rate. For the gas medium, the low inlet and high outlet are generally adopted. After the throttling of the porous sleeve, the gas medium has a volume expansion behind the valve seat, thus reducing the pressure of the medium and reducing the flow rate.
