An I-Valve Yokuvala Ephuthumayo(ESDV) iyisici esibalulekile ezinqubweni ezahlukene zezimboni, ikakhulukazi emkhakheni kawoyela negesi, lapho ukuphepha nokusebenza kahle kubaluleke kakhulu.I-ESDVzenzelwe ukumisa ngokushesha ukugeleza koketshezi noma amagesi uma kwenzeka isimo esiphuthumayo, ngaleyo ndlela zivimbele izingozi ezingaba khona njengokuvuza, ukuqhuma, noma okunye ukwehluleka okubi kakhulu.
Igama elithi “SDV” libhekisela ku-Shut Down Valve, ehlanganisa isigaba esibanzi sama-valve asetshenziselwa ukuvimba ukugeleza kwezinto emapayipini. Nakuba wonke ama-ESDV kuyi-SDV, akuwona wonke ama-SDV ahlukaniswa njengama-ESDV. Umehluko usemsebenzini othize kanye nokuphuthuma kwempendulo edingekayo. Ama-ESDV ngokuvamile asebenza ngokuzenzakalelayo yizinhlelo zokuphepha noma ngesandla ngabaqhubi ezimweni eziphuthumayo, okuqinisekisa impendulo esheshayo yokunciphisa izingozi.
Ama-ESDV afakwe izici ezahlukahlukene ezithuthukisa ukuthembeka nokusebenza kwawo. Lokhu kungafaka phakathi izindlela ezingaphumeleli, eziqinisekisa ukuthi ivalvu iyavalwa uma kwenzeka ugesi uphela, kanye namakhono okulawula kude, okuvumela opharetha ukuphatha ivalvu bekude. Umklamo nezinto ezisetshenziswa kuma-ESDV nazo zibalulekile, njengoba kumele zibhekane nokucindezeleka okukhulu kanye nezindawo ezigqwalisayo ezivame ukutholakala ezindaweni zezimboni.
Ngamafuphi, i-Emergency Shut Down Valve (ESDV) idlala indima ebalulekile ekugcineni ukuphepha emisebenzini yezimboni. Ngokuqonda ukuthi iyini i-ESDV nokuthi isebenza kanjani, abaqhubi bangaqonda kangcono ukubaluleka kwayo emasu okulungela izimo eziphuthumayo kanye nokuphendula. Ukusetshenziswa okuphumelelayo kwama-ESDV akugcini nje ngokuvikela abasebenzi kanye nemishini kodwa futhi kunegalelo ekuthembekeni kwezinqubo zezimboni, okwenza zibe yinto ebalulekile ezindaweni ezinobungozi obukhulu.
