W macnaheedu waa qor, tuur;
C-CARBON STEEL steel carbon, A, b, iyo C waxay muujinayaan qiimaha xoogga nooca birta ee hoose ilaa sare.
WCA, WCB, WCC waxay ka dhigan tahay birta kaarboon, kaas oo leh waxqabadka alxanka wanaagsan iyo xoogga farsamada.ABC waxay ka dhigan tahay heerka xoogga, sida caadiga ah loo isticmaalo WCB.Walaxda tuubada u dhiganta WCB waa inay ahaadaan A106B, iyo walxaha been abuurka ah ee u dhigma waa A105.Ku haboon valves hoos heerkulka caadiga ah iyo cadaadiska.
WC6 waa tuurista birta aluminiumka ah.Waxay leedahay iska caabin heerkul sare oo heer sare ah iyo sifooyinka antioxidant waxayna ku habboon tahay valves hoos heerkulka sare iyo xaaladaha cadaadiska sare.
Maaddada dhuumaha u dhiganta waxay ku saabsan tahay A355 P11, iyo qaybta been-abuurka ah waa A182 F11;
Intaa waxaa dheer, waxaa jira WC9, birta aluminium heerkul sare ah, oo u dhiganta qiyaastii A355 P22, iyo been-abuurka waa inuu u dhigmaa A182 F22.
Kabista alxanka ee WC waxay leedahay awood sare iyo qalafsanaan.Ku habboon codsiyada warshadaha caadiga ah.
LCB/LCC (ASTM A352) Heerkulka-hooseeya ee birta kaarboonku waxay leedahay adkaysi hoose iyo iska caabin daxalka.Waxay ku habboon tahay codsiyada heerkulka hooseeya ee heerkulka hooseeya, sida LPG gaaska dabiiciga ah (LNG).
Zfa Valves waxay soo saartaa balaaliyeyaasha caadiga ah ee WCB macaamiisha adduunka oo dhan oo leh heerkul caadi ah, sidoo kale waxaan u soo saari karnaa balaaliyeyaasha LCC ee macaamiisha Waqooyiga Yurub sida Ruushka, Finland iwm.
