W kusho ukubhala, ukulingisa;
I-C-CARBON STEEL carbon steel, A, b, kanye no-C ibonisa inani lamandla ohlobo lwensimbi ukusuka kokuphansi ukuya phezulu.
I-WCA, i-WCB, i-WCC imele i-carbon steel, enokusebenza okuhle kokushisela namandla emishini.I-ABC imele izinga lamandla, i-WCB evame ukusetshenziswa.Impahla yepayipi ehambisana ne-WCB kufanele ibe yi-A106B, futhi okuhambisanayo okukhangayo kube yi-A105.Ifanele ama-valve ngaphansi kokushisa okuvamile nokucindezela.
I-WC6 ukubunjwa kwensimbi ye-alloy.Inokumelana nokushisa okuphezulu kakhulu kanye nezakhiwo ze-antioxidant futhi ifanele ama-valve ngaphansi kwezinga lokushisa eliphezulu nezimo zokucindezela okukhulu.
Impahla yepayipi ehambisanayo imayelana ne-A355 P11, futhi ingxenye yokubumba i-A182 F11;
Ngaphezu kwalokho, kukhona WC9, high-temperature ingxubevange steel, elihambisana cishe A355 P22, futhi forging kufanele kuhambisane A182 F22.
I-WC eshiselwe ukusakaza inamandla aphezulu nobulukhuni.Ifanele izicelo ezivamile zezimboni.
I-LCB/LCC (ASTM A352) Insimbi yekhabhoni enezinga lokushisa eliphansi inokuqina okuphansi kanye nokumelana nokugqwala.Ilungele izinhlelo zokusebenza zokushisa eziphansi ze-ultra -low, njenge-LPG yegesi yemvelo (LNG).
I-Zfa Valves ikhiqiza ama-valve ovemvane e-WCB avamile kumakhasimende emhlabeni wonke ngezinga lokushisa elivamile, futhi singakhiqiza ama-valve uvemvane e-LCC Amakhasimende asuka eNyakatho Yurophu njengeRussia, iFinland njll.
ngenhla yi-WCBI-valve ye-butterfly yase-Chinakanye ne-LCCChina lug butterflyi-valve.
I-Carbon steel castings nezinto ezibunjiwe ezivame ukusetshenziswa kuma-valve
