Lub valve proportional, tseem hu ua electro-hydraulic proportional valve, yog lub valve hydraulic uas hloov cov teeb liab hluav taws xob nkag mus rau hauv kev quab yuam lossis kev hloov pauv raws li qhov sib npaug, yog li tswj tsis tu ncua xws li lub siab thiab qhov ntws. Lub valve proportional muaj ob ntu: DC proportional solenoid thiab hydraulic valve. Qhov hydraulic valve feem tsis txawv ntawm qhov dav dav hydraulic valve, tab sis DC proportional solenoid txawv ntawm cov solenoid siv nyob rau hauv lub valve dav dav. Siv cov proportional solenoid tso cai rau kev hloov pauv thiab nqus cov zis proportional rau ib qho tam sim no. Cov khoom sib npaug tuaj yeem muab faib ua peb pawg tseem ceeb raws li lawv cov kev tswj hwm: proportional pressure li qub, proportional flow valves, thiab proportional directional valves.
Lub hauv paus ntawm kev tswj tsis tu ncua nyob rau hauv proportional valve yog nyob rau hauv kev siv ntawm proportional solenoid. Thaum muaj ntau hom kev faib ua feem ntawm solenoids, lawv txoj haujlwm yooj yim yog tib yam; lawv txhua tus tau tsim los ua kom tau raws li kev tswj hwm ntawm proportional li qub.
