Ama-valve ngokusho kwemidiya ehlukene esebenzayo yokukhetha izinto zokwakha, ama-valve ajwayelekile angahlukaniswa ngokushisa okujwayelekile, izinga lokushisa eliphezulu, ukukhethwa kwempahla yokushisa ephansi, ukukhethwa kwempahla yokumelana nokugqwala, kodwa futhi ihlukaniswe ingcindezi ephansi, ingcindezi ephakathi, izinto zokukhetha i-valve ephezulu, okuyinhloko. izinto zokwakha ziyinsimbi ecijile, insimbi ecijile, insimbi engagqwali, ingxubevange yensimbi, izinga lokushisa eliphezulu insimbi, izinga lokushisa eliphansi insimbi, ukukhethwa kwepulasitiki okungagqwali.

Izinto ezivamile zevalvu:
I-1, i-valve yensimbi empunga: insimbi empunga ifanele ingcindezi ye-PN≤ 1.0mpa, izinga lokushisa -10℃ ~ 200℃ amanzi, umusi, umoya, igesi namafutha kanye neminye imidiya.Amabanga avamile ensimbi empunga yilawa: HT200, HT250, HT300, HT350.

I-2, insimbi ethambile ethambile: ilungele ingcindezi okuzisholo yona i-PN≤ 2.5mpa, izinga lokushisa lingu-30 ~ 300℃ lamanzi, umusi, umoya namafutha aphakathi nendawo, izinhlobo ezivame ukusetshenziswa yilezi: KTH300-06, KTH330-08, KTH350-10.

I-3, i-valve yensimbi eyi-nodular cast: ilungele i-PN≤ 1.6mpa, izinga lokushisa lingu-5 ~ 80℃ lamanzi, umusi, umoya namafutha kanye neminye imidiya.Izinhlobo ezivame ukusetshenziswa yilezi: QT400-15, QT450-10, QT500-7.
Uma kubhekwa izinga lamanje lobuchwepheshe basekhaya, imboni ngayinye ayilingani, futhi abasebenzisi ngokuvamile akulula ukuhlola.Ngokusho kokuhlangenwe nakho, kunconywa ukuthi i-PN≤ 2.5mpa, i-valve isakhiwe ngensimbi.

I-4, imelana ne-asidi ephezulu ye-silicon nodular cast iron: ifanele ingcindezi yokuzisholo PN≤ 0.25mpa, izinga lokushisa elingaphansi kuka-120℃ medium corrosive medium.

I-5, i-carbon steel valve: ifanele ukucindezela okuzisholo okungu-PN≤32.0MPa, izinga lokushisa elingu-30 ~ 425℃ lamanzi, umusi, umoya, i-hydrogen, i-ammonia, i-nitrogen nemikhiqizo kaphethiloli neminye imidiya.Amamaki asetshenziswa kakhulu yi-WC1, WCB, ZG25 kanye nensimbi engu-20, 25, 30 kanye nensimbi ye-alloy ephansi engu-16Mn.
