MULTI-HOLE CAGE PRESSURE REDUCING CONTROL VALVE

This series of valves adopts a multi-layer porous cage structure, allowing the design of multiple pressure reductionstages.Itisacontrolvalvespecificallydesignedforhighpressuredifferenceconditions.Itsworkingprinciple is to decompose the total pressure difference into multiple smaller pressure differentials and perform step-by-step pressure reduction, thereby effectively preventing phenomena such as cavitation, erosion, noise, flashing, and vibration. It is suitable for high pressure difference and high flow rate conditions. If the site is sensitive to noise, a noise reduction cage design can be added. Multi-stage pressure reducing control valves are widely used in power stations,chemicalengineering,petroleum,naturalgas,andotherindustries,andareparticularlysuitableforoccasions requiring precise control of high pressure fluid media.
