U-W usho ukubhala, ukuphonsa;
Insimbi yekhabhoni i-C-CARBON, u-A, u-b, no-C babonisa inani lamandla ohlobo lwensimbi kusukela phansi kuya phezulu.
I-WCA, i-WCB, i-WCC imele insimbi yekhabhoni, esebenza kahle kakhulu ekushiseni kanye namandla omshini. I-ABC imele izinga lamandla, i-WCB esetshenziswa kakhulu. Izinto zepayipi ezihambisana ne-WCB kufanele zibe yi-A106B, kanti izinto zokwakha ezihambisanayo ziyi-A105. Zifanelekela ama-valve ngaphansi kokushisa okuvamile kanye nengcindezi.
I-WC6 iwukubumba kwensimbi ye-alloy. Inezakhiwo ezinhle kakhulu zokumelana nokushisa okuphezulu kanye ne-antioxidant futhi ifaneleka kuma-valve ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu.
Izinto zepayipi ezihambisanayo zingaba ngu-A355 P11, kanti ingxenye yokwakheka yi-A182 F11;
Ngaphezu kwalokho, kukhona i-WC9, insimbi ye-alloy enokushisa okuphezulu, elingana cishe ne-A355 P22, futhi ukwakheka kufanele kuhambisane ne-A182 F22.
Ukufakwa kwe-WC okuhlanganisiwe kunamandla aphezulu kanye nobunzima. Kufanelekela ukusetshenziswa kwezimboni okuvamile.
Insimbi yekhabhoni ye-LCB/LCC (ASTM A352) Enokushisa okuphansi inokuqina okuphansi kanye nokumelana nokugqwala. Ifanele ukusetshenziswa kokushisa okuphansi kakhulu, njengegesi yemvelo ye-LPG (LNG).
Ama-Zfa Valves akhiqiza ama-valve e-butterfly e-WCB avamile kumakhasimende emhlabeni wonke anezinga lokushisa elivamile, futhi singakhiqiza ama-valve e-LCC butterfly kumakhasimende avela eNyakatho Yurophu njengeRussia, iFinland njll.
ngenhla yi-WCBI-valve yebhabhathane ye-wafer yaseShayinakanye ne-LCCIvemvane laseShayinaivalvu.

Qaphela: 1) ukwakheka kwezinto zomzimba we-valve ehlanganisiwe kukhulu, akulula ukuba namaphutha, ubukhulu besakhiwo abunamkhawulo wesikhunta, ukusebenza kwengcindezi okuthembekile, okusetshenziselwa kakhulu izimo zokucindezela okuphezulu, umoya-mpilo, ububanzi obuncane noma amanye ama-valve amancane ekukhiqizweni kwemidiya yokushisa okuphezulu, yokucindezela okuphezulu noma yokushisa okuphansi noma ekhethekile ngaphansi kokukhetha ukwakheka; ukwakheka ngokuvamile kusebenza kuphela kungcindezi ephakathi nendawo nephansi, futhi kusetshenziselwa ukwakheka okujwayelekile kwama-valve ekukhiqizweni kwesisindo.
(2) Umehluko wezinto ezibonakalayo A351 CF3M kanye ne-A182 F316L: amazinga amabili ahambisana nezinto ezibonakalayo yinsimbi engagqwali engu-316. I-CF3M ikhombisa ukuthi ukuthungwa, okuvame ukusetshenziswa njengezinto ze-valve. Ikhodi yensimbi ehambisanayo yi-A182 F316L. I-ASTM A216 WCB iyathungwa, kanti ukuthungwa kwayo yi-A105; ukuthungwa kwe-SS304 yi-A351-CF8, kanti ukuthungwa yi-A182-F304.
