Ngokukodwa iinkqubo zeekhemikhali ulwelo olukwimibhobho luhlala luyityhefu, lusebenza ngeradioactive kwaye luyingozi.Ivalve yesango lomphunga isetyenziselwa ukuthintela ukuvuza kwayo nayiphi na imichiza eyityhefu emoyeni.Isixhobo somzimba sinokukhethwa kuzo zonke izixhobo ezikhoyo, I-bellow inokunikezelwa ngezinto ezahlukeneyo ezifana ne-316Ti, 321, C276 okanye i-Alloy 625.

• 1) .Iintsimbi zentsimbi zitywina isiqu esishukumayo kwaye kwandisa ukuqina kweevalvu ezipakishiweyo zokutywina.
• 2) .Izibuko zokubeka iliso zeBellows (ukhetho): Iplagi inokudityaniswa kunye nesithuba esingentla kwemvulo ukujonga ukusebenza.
• 3) .Amatywina amabini esibini: a) Isitulo sangasemva kwindawo evulekileyo;b) Ukupakishwa kwegrafu.
• 7).Kungekhona njengesikrufu segrisi samandulo kumsonto wesiqu kuphela, Ingono yegrisi yenzelwe kwibhonethi yevalvu, sinokuthambisa isiqu, i-nut kunye ne-bushing ngqo, ngengono yegrisi;
• 8) .I-handwheel eyenzelwe i-ergonomically, ubomi benkonzo ende, kulula ukuyisebenzisa, ikhuselekile kwaye inokwethenjelwa ngakumbi;
