ʻO ke kīwaha pani e pili ana i ka huaʻōlelo puka kahi e neʻe ai ka ʻāpana pani (ʻaoʻao ākea) ma ke kikowaena o ka noho kīwaha. Wahi a kēia ʻano neʻe o ka disc kīwaha, ua kūlike ka loli o ka puka noho kīwaha me ka hahau kīwaha. ʻOiai he pōkole ka wehe ʻana a i ʻole ka pani ʻana o ke kumu kīwaha o kēia ʻano kīwaha,
Eia kekahi, he hana ʻoki hilinaʻi loa kāna, a no ka mea ua kūlike ka loli o ka puka noho valve me ka hahau ʻana o ka disc valve, kūpono loa ia no ka hoʻoponopono ʻana i ke kahe. No laila, kūpono loa kēia ʻano valve pani no ka hoʻohana ʻana ma ke ʻano he pani a hoʻoponopono a me ka throttling.
ʻO ka pōmaikaʻi maopopo loa o ka valve globe, ʻo ia ka mea, i ke kaʻina hana o ka wehe ʻana a me ka pani ʻana, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka flap ākea a me ka ʻili sila ākea ma mua o ka valve puka, no laila he pale ia i ke komo ʻana. ʻO ke kiʻekiʻe o ka wehe ʻana he 1/4 wale nō o ke anawaena o ke ala noho valve, no laila ʻoi aku ka liʻiliʻi ma mua o ka valve puka.
ʻO ka maʻamau, hoʻokahi wale nō ʻili sila ma ke kino valve a me ka disc valve o ka valve stop, no laila ua maikaʻi ke kaʻina hana o ka valve stop, a maʻalahi ka mālama ʻana i ka valve stop. Kaomi inoa a i ʻole ka pae kaomi o ka valve globe: PN1.0-16.0MPa, ANSI CLASS150-900, JIS
10-20K, ke anawaena inoa a i ʻole ke caliber: DN10 ~ 500, NPS1 / 2-36, ke ʻano pili o ka valve hoʻōki: flange, butt welding, thread, etc., ka mahana kūpono: -1969 ℃ -700 ℃,
ʻAno hoʻokele: manual, bevel gear drive, pneumatic, uila, hydraulic, gas-wai linkage, electro-hydraulic linkage,
Nā mea kino ākea: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mо2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti,
Hoʻohana ʻia nā mea like ʻole no ka hoʻoponopono ʻoki ʻana, hiki ke hoʻopili ʻia i nā ʻano media like ʻole e like me ka wai, ka mahu, ka ʻaila, ka waikawa nitric, ka waikawa acetic, ka medium oxidizing, urea, a pēlā aku.
