An Ivalvu Yokuvala Ngokungxamisekileyo(ESDV) licandelo elibalulekileyo kwiinkqubo ezahlukeneyo zoshishino, ngakumbi kwicandelo leoyile negesi, apho ukhuseleko nokusebenza kakuhle kubaluleke kakhulu.I-ESDVzenzelwe ukumisa ngokukhawuleza ukuhamba kolwelo okanye iigesi xa kukho imeko engxamisekileyo, ngaloo ndlela zithintela iingozi ezinokubakho ezifana nokuvuza, ukuqhuma, okanye ezinye iingxaki ezinkulu.
Igama elithi “SDV” libhekisa kwiValve yokuvala, equka udidi olubanzi lweevalvu ezisetyenziselwa ukumisa ukuhamba kwezinto kwiipayipi. Nangona zonke ii-ESDV ziyi-SDV, ayizizo zonke ii-SDV ezihlelwa njengee-ESDV. Umahluko usekwe kumsebenzi othile kunye nokungxamiseka kwempendulo efunekayo. Ii-ESDV zihlala zivulwa ngokuzenzekelayo ziinkqubo zokhuseleko okanye ngesandla ngabaqhubi kwiimeko ezingxamisekileyo, ukuqinisekisa impendulo ekhawulezileyo ukunciphisa iingozi.
Ii-ESDV zixhotyiswe ngeempawu ezahlukeneyo eziphucula ukuthembeka nokusebenza kwazo. Ezi zinokubandakanya iindlela ezikhuselekileyo zokungasebenzi kakuhle, eziqinisekisa ukuba ivalvu iyavalwa xa umbane ucimile, kunye nokukwazi ukulawula kude, okuvumela abaqhubi ukuba balawule ivalvu bekude. Uyilo kunye nezixhobo ezisetyenziswa kwii-ESDV nazo zibalulekile, njengoko kufuneka zimelane noxinzelelo olukhulu kunye neemeko ezirhabaxa ezihlala zifumaneka kwiindawo zoshishino.
Ngamafutshane, i-Emergency Shut Down Valve (ESDV) idlala indima ebalulekileyo ekugcineni ukhuseleko kwimisebenzi yemizi-mveliso. Ngokuqonda ukuba yintoni i-ESDV kunye nendlela esebenza ngayo, abaqhubi banokuqonda ngcono ukubaluleka kwayo kulungiselelo lwengxamiseko kunye namaqhinga okuphendula. Ukuphunyezwa ngempumelelo kwee-ESDV akugcini nje ngokukhusela abasebenzi kunye nezixhobo kodwa kukwanegalelo ekuthembekeni ngokubanzi kweenkqubo zemizi-mveliso, nto leyo eyenza ukuba zibe yimfuneko kwiindawo ezinomngcipheko ophezulu.
