Butterfly valvesti le thli phunphun a luannak uk khawhnak ah a biapi tukmi rian an ttuan. Butterfly valve phun dangdang lakah, lug butterfly valve le waferbutterfly valvesa tam deuh nih hmanmi thimnak pahnih an si. Valve phun hnih hna nih hin riantuannak aa dangmi an ngei i hmannak pakhatkhat caah aa tlakmi an si.TWShi capar ah an i lawhnak le an i dannak kha kan hlathlai lai, aa tlakmi valve na thim tikah theihhngalhmi biakhiahnak tuah khawhnak ding caah bawmhchanh ding ruahchannak he.
I. An i lawhnak hna.
1. RiantuanPphunglam.
Wafer phun butterfly valve le lug phun butterfly valve pahnih nih valve disc kha thlennak in a luannak kha an uk. Valve disc aa mernak angle cu 0 in 90 degree karlak lawng a si kho, cucu, valve cu 90 degree ah a ong dih i 0 degree ah a khar dih tinak a si. Mah cu butterfly valve hna riantuan ning phunglam a si.
2. Aa khatmiHmaitonh
Wafer butterfly valve le lug butterfly valve cu a tlawm deuhmi phun in sermi an si, hmun tlawm deuh an lak i hmun tlawmte lawng a ngeimi pipeline system ah chiah awkah aa tlak.
3. A tlarimi suaisam:
An pahnih in ramkip riantuannak phunglam he aa tlak, phunglam flanges he pehtlaih a fawi, cun a um cangmi system ah fawi tein thlen khawh an si.

II.Zeidah's aa dannak?
Wafer phun butterfly valve le lug phun butterfly valve pahnih nih hin butterfly valve pehtlaihnak phun kha a chim duhmi a si, a sau ning aa khat i aa khatmi tinhmi a ngei, asinain suaisamnak, chiahnak, hmannak, man le a dangdang ah aa dannak a um.
1.DesignDthleidannak
Lug butterfly valve: Valve pum a donghnak pahnih cu hri in sermi lugs in sermi an si, cu hna cu valve remhnak caah a ttha deuhmi an si.
Wafer butterfly valve: Cu he aa ralchanh in, hri aa telmi a ngei lo, asinain flange pahnih karlak ah aa hren, pipeline flange le valve pum chungin bolt a kal i remh a si. Cucu, pipeline flange a hrenmi bolt hna nih an hneknak nih a sermi a si tinak a si.
2.ChiahnakProcess.
Lug butterfly valves cu zungzal zohkhenh a herhmi asiloah tthen lengmang a herhmi pipeline caah aa tlak. Threaded inserts cu pipeline system dihlak hrawh loin chiah le phoih a fawi. A chuakmi butterfly valve cu pipeline donghnak ah chiah khawh a si i a donghnak valve ah hman khawh a si.
- Valve pum cung ah hnahnawhnak hrial khawhnak dingah lugs pawl cu flange bolts he aa tlak tein an i tluk ti kha zohfel.
- A herh tikah aa tlakmi gasket thilri hmang law a luannak khamnak caah, a hlei in a tlawm deuhmi thli luhchuahnak system ah.
- Valve chung ah aa khatmi hneknak a um khawh nakhnga hri pawl kha aa tluk tein hren.
Wafer butterfly valves cu hmunhma a tlawmnak hmun ah pipeline a donghnak pahnih pehtlaihnak caah aa tlak deuh, asinain an i tthen khawh caah terminal valve ah hman khawh an si lo.
- A khar khawh nakhnga flange aa tlak le tlak lo (eg ANSI, DIN) zohfel.
- Seh thilri a rawhnak hnga lo flange bolt pawl kha a hlei in hren kha hrial.
- A tlawm bik pipeline hninhnak he system chungah chiah a si i a tthawn lonak hnga.
3. Hrennak Mechanism.
Lug butterfly valve nih hri aa pehtlaimi pehtlaihnak le himnak thir hri ruangah a fek deuhmi kharnak a pek, a luang lomi riantuan khawhnak le ti a kir tthan lonak hnga a kham.
Cu he aa ralchanh in, wafer phun butterfly valve cu zumhawktlak tein kharnak hmuh khawhnak ding caah flange pahnih karlak ah hneknak ah aa hngat, cucaah aa tlak lonak le a luannak hrial khawhnak ding caah pipeline he aa tlak dih in chiah a hau.
4. DN&PN
- Wafer on butterfly valves cu a tlangpi in DN600 nakin a hme deuh, cun single flange butterfly valves cu diameter ngan deuh caah hman khawh a si. Annih cu a tlangpi in hneknak ≤ PN16 a simi thil sining caah aa tlak.
-Lug butterfly valve cu a kau deuh i PN25 tiang a sang deuhmi hneknak a tuar khawh, zeicahtiah lug butterfly valve chiah cu a him deuh.
5. Cost
Lug butterfly valves le wafer butterfly valves cu man tlawmternak ah an i dang.
Wafer butterfly valves cu a tlangpi in a man a fawi deuh, zeicahtiah an suaisam a sawhsawh deuh, an tuah ning a fawi deuh, cun thilri tlawm deuh an herh.
Lug butterfly valve nih hri a herh, cucaah sernak kalning cu a har ngai.
III. Cdonghnak
Lug butterfly valve le wafer butterfly valve pahnih hi ti a luannak uk khawhnak caah hman an si, asinain hi pahnih karlak ah hin suaisamnak, chiahnak, kharnak, kauhnak, hneknak tlukruannak le man ah aa dannak a um. Thim tikah, a herhmi thil sining ning in tuak khawh a si: tthen le zohkhenh a herh lengmang ahcun, a chuakmi hnakhaw phun thim a ṭha; Hmun a tlawm i man a fak ahcun, suaisamnak ah wafer cu aa tlak deuh. Hi aa dannak hna hngalhthiamnak nih aa tlak deuhmi valve thim khawhnak le ttha tein le zumhawktlak tein luannak uk khawhnak ah a bawmh khawh.TWSa ttha ngaimi caah zumhawktlak hawikom lawng si loinbutterfly valves, asinain a thukmi thiamnak khonnak le a tthangchomi a phichuak zong a ngeikutka valves, check valves, thli chuahnak valve, tbk. Zeibantuk ti uknak nih an in herh zongah, thiamsang le a tlingmi pakhat-stop valve bawmhnak kan in pek khawh. Riantuantinak asiloah thiamnak lei ruahnak cheuhnak na ngeih ahcun, zeitik caan paoh ah zalong tein kanmah he pehtlaihnak tuah khawh a si.
