Iindidi ezintathu zeevalvu zokutshekisha -ivalve yokujonga iwafer, ivalve yokukhangela i-flange, kunye ne-valve yokukhangela i-swing flanged - zonke zibonelela ngeenzuzo ezihlukeneyo malunga nokusebenza kunye nokusetyenziswa.
Ivalve yokujonga iwafer igqame kuyilo lwayo olubambeneyo kunye nolwakhiwo olukhaphukhaphu. Olu phawu lwenza kube lukhetho olufanelekileyo kwizicelo apho indawo incinci okanye ubunzima buyinkxalabo. Ngaphezu koko, uyilo lwe-wafer lwenza kube lula ukufakwa phakathi kweeflange, okukhokelela ekunciphiseni ixesha lofakelo kunye neendleko.
Iiflange faka ivalve yokukhangela idume ngomsebenzi wayo wokutywina ngokugqibeleleyo. Ukufakwa kweflange kusebenza njengegaskets phakathi kwevalve kunye neflange, iqinisekisa isitywina esikhuselekileyo esithintela nakuphi na ukuvuza. Olu phawu lwenza ukuba ivalve yokukhangela iflange igqibelele kusetyenziso olunoxinzelelo oluphezulu apho ukugcina ingqibelelo yokutywina kubalulekile.
Ekugqibeleni, iivalve yokukhangela ijingiikhethwa ngenxa yokuguquguquka kwayo kunye nokuthembeka. I-disc ye-swinging ngaphakathi kwevalve ivumela ukulawula ukuhamba kakuhle. Olu hlobo lwevalve yokutshekisha lufanelekile ngokukodwa kwizicelo apho ukuthintela umva kubalulekile, njengoko indlela yokuguqula ilawula ngokufanelekileyo ukuhamba okubuyela emva.
