Lub npe tag nrho ntawm proportional valve yog electro-hydraulic proportional valve. Nws yog lub valve hydraulic uas hloov cov teeb liab hluav taws xob nkag mus rau hauv kev quab yuam lossis kev hloov pauv hauv kev faib ua feem, yog li txhawm rau tswj tsis tu ncua xws li siab thiab ntws. Lub proportional valve yog tsim los ntawm DC proportional solenoid thiab hydraulic valve. Qhov hydraulic valve feem tsis txawv ntawm qhov dav dav hydraulic valve, tab sis DC proportional electromagnet txawv ntawm electromagnet siv nyob rau hauv lub dav solenoid valve. Qhov tso zis tawm thiab nqus cov zis proportional rau qhov muab tam sim no tuaj yeem tau los ntawm kev siv cov khoom siv hluav taws xob proportional. Cov khoom sib npaug tuaj yeem muab faib ua peb pawg: proportional pressure li qub, proportional flow valves, thiab proportional directional li qub raws li lawv cov kev tswj tsis tau.
