ʻO ED Series Wafer butterfly valve he ʻano lima lima palupalu a hiki ke hoʻokaʻawale i ke kino a me ke ʻano wai.
Mea o na Mahele Nui:
| Nā ʻāpana | Mea waiwai |
| Kino | CI,DI,WCB,ALB,CF8,CF8M |
| Disc | DI, WCB, ALB, CF8, CF8M, Puke Laina Rubber, kila kuhiliʻole Duplex, Monel |
| Ke kumu | SS416,SS420,SS431,17-4PH |
| Noho | NBR, EPDM, Viton, PTFE |
| Pin liʻiliʻi | SS416,SS420,SS431,17-4PH |
ʻŌlelo no ka noho:
| Mea waiwai | Mahana | E hoʻohana i ka wehewehe |
| NBR | -23 ℃ ~ 82 ℃ | ʻO Buna-NBR: (Nitrile Butadiene Rubber) maikaʻi ka ikaika tensile a me ke kū'ē i ka abrasion. He mea kū'ē hoʻi ia i nā huahana hydrocarbon. ʻAʻole hiki ke hoʻohana ʻo Buna-N no ka acetone, ketones a me ka hydrocarbons nitrated a i ʻole chlorinated. |
| Ka manawa pana-23 ℃ ~120 ℃ | ||
| EPDM | -20 ℃~130 ℃ | ʻO ka Lapa EPDM maʻamau: he lāʻau synthetic maikaʻi i hoʻohana ʻia i loko o ka wai wela, nā mea inu, nā ʻōnaehana huahana waiū a me nā mea i loaʻa nā ketones, ka waiʻona, nā nitric ether esters a me ka glycerol. Akā ʻaʻole hiki i ka EPDM ke hoʻohana no nā aila hydrocarbon, nā minerala a i ʻole nā mea hoʻoheheʻe. |
| Ka manawa pana-30 ℃ ~ 150 ℃ | ||
| Viton | -10 ℃~ 180 ℃ | ʻO Viton kahi fluorinated hydrocarbon elastomer me ke kūpaʻa maikaʻi loa i ka hapa nui o nā aila hydrocarbon a me nā kinoea a me nā huahana ʻē aʻe. ʻAʻole hiki iā Viton ke hoʻohana no ka lawelawe mahu, ka wai wela ma luna o 82 ℃ a i ʻole ka alkalines concentrated. |
| PTFE | -5 ℃ ~ 110 ℃ | PTFE i maikai kemika hana paʻa a me ka ili e ole sticky.At ka manawa like, he maikai lubricity waiwai a me ka elemakule kū'ē. He mea maikaʻi ia no ka hoʻohana ʻana i nā waikawa, alkalis, oxidant a me nā corrodents ʻē aʻe. |
| (EdPM laina loko) | ||
| PTFE | -5 ℃~90 ℃ | |
| (NBR laina loko) |
Hana:lever, pahu pahu, mea hana uila, mea hana pneumatic.
Nā hiʻohiʻona:
1.Stem poʻo hoʻolālā o Double "D" a i ʻole Square cross: Maʻalahi e hoʻohui me nā mea hana like ʻole, e hāʻawi i nā torque hou aʻe;
2.Two piece stem square Keaukaha:No-space pili pili i kekahi ilihune kūlana;
3.Ke kino me ka ʻole o ka hoʻolālā ʻana: Hiki i ka noho ke hoʻokaʻawale i ke kino a me ke ʻano wai kūpono, a kūpono hoʻi me ka flange paipu.
