An Ingxamiseko ivaliwe ivalve(I-ESDV) licandelo elibalulekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso, ngakumbi kwicandelo leoyile negesi, apho ukhuseleko kunye nokusebenza kakuhle kukuphazamiseka.I-ESDVzenzelwe ukukhawulezisa ukuhamba kwee-fluid okanye iigesi kwimeko yongxamiseko, ngokwenza oko kuthintelwe iingozi ezinokubakho, ukuqhuma, okanye ezinye iingozi zentlekele.
Ibinzana elithi "sdv" libhekisa ekuvaleni ivalve, equka udidi olubanzi lweevalves ezisetyenziselwa ukumisa ukuhamba kwezinto kwimibhobho. Ngelixa zonke i-ESDVs zii-SDVs, ayizizo zonke ii-SDVs ezihlelwe njenge-ESDVs. Umahluko ulele kumsebenzi othile kunye nokungxamiseka kwempendulo efunekayo. I-ESDVs iqhele isebenza ngokuzenzekelayo ngenkqubo yokhuseleko okanye eyenziwa ngesandla ngabaqhubi kwiimeko ezingxamisekileyo, ukuqinisekisa impendulo ekhawulezileyo kunciphisa umngcipheko.
I-ESDVs ixhotyiswe ngeendlela ezahlukeneyo ezikhuthaza ukuthembeka kwabo kunye nokusebenza. Ezi zinokubandakanya iindlela ezikhuselekileyo ezikhuselekileyo, eziqinisekisa ukuba iveli ivaliwe kwimeko yokungaphumeleli kwamandla, kunye nokulawula kude, ukuvumela abaqhubi, bavumela abaqhubi, bavumela abaqhubi, balawule ivalve kumgama okhuselekileyo. Uyilo kunye nezixhobo ezisetyenziswa kwi-ESDVs zibalulekile, njengoko kufuneka zikwazi ukumelana neengcinezelo ezigqithileyo kunye neemeko zoncedo zihlala zifumaneka kwizicwangciso zemizi-mveliso.
Kwisishwankathelo, i-parivery ivaliwe ivalve (i-Esdv) idlala indima ebalulekileyo ekugcineni ukhuseleko kwimisebenzi yemveliso. Ngokuqonda ukuba yintoni i-ESDV kunye nendlela esebenza ngayo, abaqhubi banokuluxabisa ngakumbi ukubaluleka kwayo kwizicwangciso-qhinga zenkqubela phambili kunye neendlela zokuphendula. Ukuphunyezwa ngokukuko kwe-ESDVs kungakhuseleki nje kuphela abasebenzi kunye nezixhobo kodwa ikwanegalelo kwingqibelelo yeenkqubo zokushishina, ibenza babe nakho ukubandakanyeka kwiindawo ezinomngcipheko omkhulu.
