I-valve ye-proportional ibizwa ngokuthi i-electro-hydraulic proportional valve, okuwuhlobo lwe-hydraulic valve eguqula isignali kagesi efakiwe isebenze noma igudluke ngokulinganayo, ukuze ilawule ngokuqhubekayo ingcindezi, ukugeleza nezinye imingcele. I-valve ye-proportional yakhiwe yi-DC proportional electromagnet kanye ne-hydraulic valve. Ingxenye ye-valve ye-hydraulic ihluke kancane ku-valve ejwayelekile ye-hydraulic, kanti i-electromagnetic proportional electromagnet ye-DC ihlukile kumagnetbuzibuthe osetshenziswa ku-valve evamile ye-solenoid, futhi okukhiphayo okuphumayo kanye nokudonsayo kungatholakala ngokulingana namanje owanikwa ngokusebenzisa i-proportional electromagnet. . I-valve ye-proportional ngokusho kwemingcele yayo yokulawula ingahlukaniswa nge-valve ye-proportional pressure, i-proportional flow valve, i-proportional direction valve izigaba ezintathu.
Ngokuthuthukiswa kokudluliselwa kwe-hydraulic kanye nezinhlelo ze-hydraulic servo, ezinye izinhlelo ze-hydraulic ezidinga ukulawulwa okuqhubekayo kokucindezela, ukugeleza kanye nesiqondiso ngaphandle kokunemba kokulawula okuphezulu kuye kwavela ekusebenzeni kokukhiqiza. Njengoba izingxenye ze-hydraulic ezijwayelekile zingakwazi ukugcwala ngokwanele ukuba zibe nezidingo ezithile ze-servo, futhi ukusetshenziswa kwama-valve e-servo e-electro-hydraulic kuwukumosha kakhulu ngoba izidingo zokunemba kokulawula aziphezulu, i-valve yokulawula ngokulinganayo phakathi kwezingxenye ezijwayelekile ze-hydraulic (switch control) futhi i-servo valve (ukulawula okuqhubekayo) iye yakhiqizwa eminyakeni yamuva.
I-electro-hydraulic proportional control valve (okubizwa ngokuthi i-proportional valve) iwuhlobo lwevalvu yokulawula eshibhile ye-electro-hydraulic enokusebenza okuhle kokunqanda ukunukubezeka. Ukuthuthukiswa kwe-valve ye-proportional valve kuhlangabezana nezindlela ezimbili, enye iwukuba esikhundleni somshini wokufaka wokulungisa owenziwe ngesandla we-valve ye-hydraulic yendabuko nge-proportional electromagnet, ngesisekelo se-valve ye-hydraulic yendabuko: ukuthuthukiswa kokuhlukahluka kokuqondisa okulinganayo, ukucindezela kanye nama-valve okugeleza; Okwesibili ukuthi abanye abakhiqizi bangempela be-electro-hydraulic servo valve bathuthukiswe ngemuva kokunciphisa ukuklama nokukhiqiza ngokunemba ngesisekelo sama-valve e-electro-hydraulic servo.
