Iivalvu zesango ezibunjiweyo kunyeivelufa yesango yentsimbi eyenziweyoyimizekelo enenzuzo yeevalvu zesango ezinezi mpawu zilandelayo ezibalaseleyo.
Ekuqaleni,ivelufa yesango elibunjiweyokunye neevalvu zesango zentsimbi ezibunjiweyo zenziwe kusetyenziswa inkqubo yokuqinisa amandla aphezulu, kwaye ngoko ke inokumelana noxinzelelo oluhle kakhulu. Iivalvu zeglobhu ezenziwe ngolu hlobo zinokumelana noxinzelelo oluphezulu kunye nemekobume yobushushu obuphezulu, kwaye zifanelekile kwizicelo zemizi-mveliso ezifuna uxinzelelo oluphezulu, njengemichiza, i-petroleum, kunye namashishini egesi yendalo.
Okwesibini, iivalvu zeglowubhu ezibunjiweyo kunye neevalvu zeglowubhu zentsimbi ezibunjiweyo zinomsebenzi olungileyo wokutywina. Uyilo lwesakhiwo kunye nokukhethwa kwezinto zevalve kuqinisekisa ukutywinwa okuqinileyo kwaye kuthintela ngokufanelekileyo nakuphi na ukuvuza ukuba kwenzeke. Oku kutywinwa kuthembekileyo kwenza ukuba ivalve yeglowubhu ikwazi ukusebenza ngokukhuselekileyo kwiindawo ezisebenza nzima kwaye ikhusele ukhuseleko lwemibhobho yolwelo.
Ukongeza, iivalvu zeglowubhu ezibunjiweyo kunye neevalvu zeglowubhu zentsimbi ezibunjiweyo zineempawu zokuchasana nokuhamba okuphantsi. Isakhiwo sangaphakathi se-valve kunye noyilo lweepaseji zamanzi zivumela umbane ukuba udlule kakuhle, ukunciphisa ukuchasana nokuhamba. Oku akugcini nje ukuphucula ukusebenza kakuhle kwenkqubo, kodwa kunciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza.
