An Valavu Yotseka Mwadzidzidzi(ESDV) ndi gawo lofunika kwambiri pa ntchito zosiyanasiyana zamafakitale, makamaka m'gawo la mafuta ndi gasi, komwe chitetezo ndi magwiridwe antchito ndizofunikira kwambiri.ESDVapangidwa kuti aletse kuyenda kwa madzi kapena mpweya mwachangu pakagwa ngozi, motero amaletsa zoopsa monga kutuluka kwa madzi, kuphulika, kapena kulephera kwina kwakukulu.
Mawu akuti "SDV" amatanthauza Shut Down Valve, yomwe imaphatikizapo gulu lalikulu la ma valve omwe amagwiritsidwa ntchito kuletsa kuyenda kwa zinthu m'mapaipi. Ngakhale ma ESDV onse ndi ma SDV, si ma SDV onse omwe amagawidwa ngati ma ESDV. Kusiyana kuli mu ntchito yeniyeniyo komanso kufunikira kwa yankho lofunikira. Ma ESDV nthawi zambiri amayatsidwa okha ndi machitidwe achitetezo kapena ndi ogwira ntchito pamanja pakagwa ngozi, kuonetsetsa kuti akuyankha mwachangu kuti achepetse zoopsa.
Ma ESDV ali ndi zinthu zosiyanasiyana zomwe zimawonjezera kudalirika kwawo komanso magwiridwe antchito. Izi zitha kuphatikizapo njira zotetezera kulephera, zomwe zimaonetsetsa kuti valavu imatseka ngati magetsi alephera, komanso mphamvu zowongolera kutali, zomwe zimathandiza ogwiritsa ntchito kuyendetsa valavuyo patali. Kapangidwe ndi zipangizo zomwe zimagwiritsidwa ntchito mu ma ESDV ndizofunikiranso, chifukwa ziyenera kupirira kupsinjika kwakukulu ndi malo owononga omwe nthawi zambiri amapezeka m'malo opangira mafakitale.
Mwachidule, Vavu Yotseka Pangozi (ESDV) imagwira ntchito yofunika kwambiri pakusunga chitetezo m'mafakitale. Pomvetsetsa kuti ESDV ndi chiyani komanso momwe imagwirira ntchito, ogwira ntchito amatha kuzindikira bwino kufunika kwake pakukonzekera zadzidzidzi komanso njira zothanirana ndi mavuto. Kugwiritsa ntchito bwino ma ESDV sikuti kumateteza antchito ndi zida zokha komanso kumathandizira kuti ntchito zonse zamakampani zikhale zotetezeka, zomwe zimapangitsa kuti zikhale zofunikira kwambiri m'malo omwe ali pachiwopsezo chachikulu.
