ductile iron rubber seal butterfly valve

ʻO VAG kahi mea hana valve honua e hāʻawi i nā hoʻonā i nā pilikia pili wai. Ma mua o 140 mau makahiki, ua hoʻolako ka hui i nā huahana kiʻekiʻe a me nā lawelawe mālama ʻoihana no ka wai a me nā māla wai. Loaʻa iā VAG ma mua o 10 mau pūʻulu huahana, kēlā me kēia me ka nui o nā huahana 28, a hāʻawi i kahi ākea ākea. I nā makahiki he 50 i hala iho nei, ua hoʻomohala ʻo VAG i nā valve butterfly a hana i nā mana hou he nui i kūpono no nā ʻoihana like ʻole. ʻAʻole lākou i hoʻohana wale ʻia i ka ʻoihana wai, akā i loko o ka wai ʻino, ke kinoea maoli a me nā ʻoihana kai. Loaʻa i ka hui huahana valve butterfly he 16 mau pahu like ʻole no nā kumu like ʻole. ʻAʻole wale nā ​​loli i ka māhele noi, akā i ke ʻano o ka hana. Hoʻohana ʻia ka valve e ka huila lima, ka mea hana uila, ka mea hana hydraulic a i ʻole ka mea hana pneumatic. Hoʻokahi pū kekahi me ka VAG HYsec hydraulic brake a me ka mea hāpai. Hiki i ka mālama maʻamau ke hōʻoia i ka hoʻohana palekana a me ka lōʻihi o nā valve ma nā kikowaena lawelawe VAG a ma ka honua holoʻokoʻa. No ka maʻalahi o kēia kaʻina hana, hāʻawi ʻo VAG i nā ʻaelike mālama e mālama i ka maikaʻi a me ka hilinaʻi. ʻO kaʻoiaʻiʻo, hāʻawi ka hui i nā limahana lawelawe a me nā pilina, mākaukau e kōkua i nā mea kūʻai aku i kahi e pono ai ke kōkua. Hāʻawi kā mākou poʻe loea ʻenehana mai ka hui kūkākūkā i ke kākoʻo ʻenekinia no nā hoʻonā kūikawā me kā lākou ʻike loea hohonu a me nā mea e pili ana i ka pale ʻana i nā hewa a me nā pōʻino. Ke nānā nei i ke kumukūʻai a pau o ke kuleana (TCO) o kahi valve, ʻaʻole wale ke kumukūʻai ka mea nui, akā ʻo ka loaʻa wikiwiki hoʻi, ka manawa pōkole loa, ke ola lawelawe, a me nā mea ʻē aʻe e like me nā ʻāpana ʻokoʻa kiʻekiʻe. ʻAʻole hāʻawi wale ʻo VAG i kēia mau ʻāpana ʻāpana no kāna mau huahana a pau, akā hāʻawi pū i kēia mau ʻāpana ʻāpana no nā valve i hana ʻia e nā ʻaoʻao ʻekolu.
