Ivalve elinganayo ibizwa ngokuba yi-electro-hydraulic proportional valve, luhlobo lwevalvu yombane eguqula igalelo lombane libe linyanzele okanye lifuduke ngokulinganayo, ukuze lilawule ngokuqhubekayo uxinzelelo, ukuhamba kunye nezinye iiparamitha. Ivalve yolungelelwaniso yenziwe yi-DC yombane wokulinganisa we-electromagnetic kunye nevalve yehydraulic. Inxalenye yevalve ye-hydraulic yahluke kancinane kwivalve ye-hydraulic jikelele, kwaye i-DC proportional electromagnet yahlukile kwi-electromagnetic esetyenziswa kwivalve ye-solenoid ngokubanzi, kwaye imveliso yokufuduswa kunye nemveliso yokufunxa inokufunyanwa ngokuhambelana nomsinga onikiweyo ngokusebenzisa i-electromagnetic electromagnet. . Ivalve elinganiselayo ngokweeparamitha zayo zolawulo inokwahlulwa ibe ivelufa yoxinzelelo olulinganayo, ivelufa ehambelanayo, ivalve yendlela yolungelelwaniso iindidi ezintathu.
Ngokuphuhliswa kwe-hydraulic transmission kunye ne-hydraulic servo systems, ezinye iinkqubo ze-hydraulic ezifuna ukulawulwa okuqhubekayo koxinzelelo, ukuhamba kunye nolwalathiso ngaphandle kokuchaneka kokulawula okuphezulu kubonakala kwimveliso yokuvelisa. Ekubeni amacandelo e-hydraulic aqhelekileyo awakwazi ukugcwala ngokwaneleyo ukuba abe neemfuno ezithile ze-servo, kunye nokusetyenziswa kweevalvu ze-servo ze-electro-hydraulic yinkcitho kakhulu kuba iimfuno zokulawula ukuchaneka aziphezulu, ivalve yokulawula ngokulinganayo phakathi kwezinto eziqhelekileyo ze-hydraulic (ulawulo lokutshintsha) kunye nevalve ye-servo (ulawulo oluqhubekayo) iveliswe kwiminyaka yakutshanje.
Ivalve yolawulo lwe-electro-hydraulic proportional control (ekubhekiswa kuyo njengevalve yolungelelwaniso) luhlobo lwevalvu yokulawula ephantsi kwe-electro-hydraulic esebenza kakuhle yokuchasana nongcoliseko. Uphuhliso lwevalufa yolungelelwaniso namava eendlela ezimbini, enye kukutshintsha indlela yokufaka uhlengahlengiso lwemanuwali yevalve yendalo yoxinzelelo lwehydraulic kunye ne-electromagnetic electromagnet, ngokwesiseko sevalve ye-hydraulic yemveli: uphuhliso lweendlela ezahlukeneyo zolungelelwaniso, uxinzelelo kunye neevalvu zokuhamba; Okwesibini kukuba abanye abavelisi bevalvu ye-electro-hydraulic servo yantlandlolo baphuhliswe emva kokunciphisa uyilo kunye nokuveliswa kokuchaneka ngokwesiseko se-electro-hydraulic servo valves.
