I-valve yensimbi ehlanganiswe ngokugcwele iyi-valve evamile kakhulu, isici sayo esiyinhloko ukuthi ngenxa yokuthi ibhola kanye nomzimba we-valve kuhlanganiswe ucezu olulodwa, i-valve akulula ukukhiqiza ukuvuza ngesikhathi sokusetshenziswa.Ngokuyinhloko yakhiwe umzimba we-valve, ibhola, isiqu, isihlalo, i-gasket nokunye.Isiqu sixhunywe kusondo lesandla se-valve ngebhola, futhi isondo lesandla liyazungeziswa ukuze liphendule ibhola ukuze livule futhi livale ivalvu.Izinto zokukhiqiza ziyahlukahluka ngokuya ngokusetshenziswa kwezindawo ezahlukahlukene, imidiya, njll., ikakhulukazi i-carbon steel, insimbi engagqwali, i-alloy steel, insimbi ekhonjiwe, njll.
