Valavu yofananira imatchedwa electro-hydraulic proportional valve, yomwe ndi mtundu wa hydraulic valve yomwe imasintha chizindikiro chamagetsi kuti chizigwira mwamphamvu kapena kusuntha molingana, kuti chiziwongolera mosalekeza kukakamiza, kuyenda ndi magawo ena. Vavu yofananira imapangidwa ndi ma electromagnetic a DC ndi hydraulic valve. Gawo la valavu ya hydraulic ndi losiyana pang'ono ndi ma hydraulic valve, ndipo ma electromagnetic a DC ndi osiyana ndi ma electromagnet omwe amagwiritsidwa ntchito mu valavu ya solenoid, ndipo kutulutsa kotulutsa ndi kuyamwa kumatha kupezedwa molingana ndi zomwe zapatsidwa pogwiritsa ntchito ma electromagnetic proportional. . Vavu yofananira molingana ndi magawo ake owongolera imatha kugawidwa mu valavu yofananira, valavu yoyenda molingana, valavu yoyendera magawo atatu.
Ndi chitukuko cha ma hydraulic transmission and hydraulic servo systems, machitidwe ena a hydraulic omwe amafunikira kulamulira kosalekeza kwa kupanikizika, kutuluka ndi kuwongolera popanda kuwongolera kwakukulu kwawonekera pakupanga. Popeza zigawo za hydraulic wamba sizingakhale zodzaza kuti zikhale ndi zofunikira zina za servo, komanso kugwiritsa ntchito ma electro-hydraulic servo mavavu ndi owononga kwambiri chifukwa zofunikira zowongolera sizili zapamwamba, valavu yowongolera molingana pakati pa zigawo wamba za hydraulic (kusintha kosintha) ndi valavu ya servo (kuwongolera mosalekeza) yapangidwa m'zaka zaposachedwa.
Electro-hydraulic proportional control valve (yotchedwa proportional valve) ndi mtundu wa valve yotsika mtengo ya electro-hydraulic control valve yokhala ndi ntchito yabwino yolimbana ndi kuipitsidwa. Kukula kwa valavu yofananira kumakumana ndi njira ziwiri, imodzi ndikusintha njira yosinthira pamanja ya valavu yamtundu wa hydraulic yokhala ndi ma electromagnet yofananira, pamaziko a valavu yamtundu wa hydraulic: kukulitsa njira zosiyanasiyana zofananira, kuthamanga ndi ma valve otaya; Chachiwiri ndi chakuti ena oyambirira opanga ma electro-hydraulic servo valve amapangidwa atachepetsa mapangidwe ndi kupanga zolondola pamaziko a ma electro-hydraulic servo valves.
