TOP-GUIDE-POROUS-CAGE-CONTROL-VALVE-Diagram

Due to the large pressure difference of working condition and the fast fow rateof medium, the valve internals will be seriously damaged by erosion and generatea lot of noise, so our company changed the window type standard sleeve to porous sleeve. For the general fow direction of liquid, it is from the valve high in and lowout. Through porous throttling, the medium collides in the sleeve, and the internalconsumption can reduce the fow rate. As for the gas medium, low inlet and highoutlet are generally adopted, so that the gas medium has a volume expansion behindthe valve seat after throttling through the porous sleeve, so as to reduce the pressureof the medium and reduce the fow rate.
