Ko te tikanga o te W ko te tuhituhi, ko te maka;
RINO WARO-C Ko te rino waro, A, b, me C e tohu ana i te uara kaha o te momo rino mai i te iti ki te teitei.
Ko te WCA, WCB, WCC e tohu ana i te maitai waro, he pai te mahi whakarewa me te kaha miihini. Ko te ABC e tohu ana i te taumata kaha, ko te WCB e whakamahia whānuitia ana. Ko te rauemi paipa e rite ana ki te WCB me A106B, ā, ko te rauemi hanga e rite ana ko A105. He pai mō ngā takirere i raro i te pāmahana me te pēhanga tikanga.
Ko te WC6 he whakarewanga o te maitai koranu. He tino pai tōna ātete ki te pāmahana teitei me ōna āhuatanga ārai mate, ā, he pai hoki mō ngā takirere i raro i ngā āhuatanga pāmahana teitei me te pēhanga teitei.
Ko te rauemi paipa e rite ana ko te A355 P11, ā, ko te wāhanga hanga ko te A182 F11;
Hei tāpiritanga, kei reira te WC9, te maitai koranu pāmahana-teitei, e rite ana ki te A355 P22, ā, me rite te hanga ki te A182 F22.
He kaha, he pakeke hoki te whakarewanga WC. He pai mō ngā mahi ahumahi tuku iho.
He iti te pakari me te ātete ki te waikura o te maitai waro pāmahana-iti LCB/LCC (ASTM A352). He pai mō ngā whakamahinga pāmahana-iti rawa, pērā i te hau māori LPG (LNG).
Ka hangaia e Zfa Valves ngā takirere pūrerehua WCB noa mō ngā kiritaki puta noa i te ao me te pāmahana noa, ā, ka taea hoki e mātou te whakaputa i ngā takirere pūrerehua LCC mō ngā kiritaki mai i te Raki o Ūropi pērā i a Rūhia, Finland me ētahi atu.
