Ifaneleka ngokukhethekile ukuba ipuleti uvemvane levalvu yezinga elikhulu lifakwe ohlangothini lwephayiphi ububanzi.Ku-butterfly valve body cylindrical channel, i-disc disc ezungeze i-eksisi yokuzungezisa, i-engeli yokuzungezisa phakathi kuka-0°~90°, ukuzungezisa ukuya ku-90°, i-valve iyisimo esivuleke ngokugcwele.Isakhiwo saso silula, izindleko eziphansi, ububanzi obuguquguqukayo bukhulu.
I-Butterfly valve seal iyirabha njengomxhumanisi, ikude ne-valve yebhola ewuhhafu, i-valve yebhola, i-valve yesango yensimbi yokuvala ukusebenza kanzima.I-valve ye-half ball ngemva kokusetshenziswa isikhathi eside, isihlalo siphinde sikhiqize iminonjana yokugqoka, sizoqhubeka sisetshenziswa, ngokulungisa isiqu nokupakisha inqubo yokuvula nokuvala i-valve stem nje ukushintshanisa 90 °, kwakukhona izimpawu zokuvuza, ukucindezelwa ukupakisha indlala bolts futhi kancane, ukupakisha kungenziwa ngaphandle kokuvuza, kuyilapho enye kusenamandla amancane ama-valve avuzayo, ukuvuza okukhulu ku-valve.
Kukhona ukuqhathanisa uvemvane valve kuyinto ezintathu eccentric metal hard seal butterfly valve, umzimba valve futhi isihlalo izingxenye ezihlanganisiwe, isihlalo uphawu ebusweni ungqimba olungaphezulu lokushisa Welding, ukugqwala ukumelana ingxubevange impahla.Indandatho yokuvala isitaki esithambile enezingqimba eziningi egxilwe epuletini le-valve, le valve yovemvane uma iqhathaniswa ne-valve yovemvane yendabuko inokumelana nezinga lokushisa eliphezulu, ukusebenza okukhanyayo, akukho ukuvulwa nokuvala ukungqubuzana, ukuvala nge-torque yendlela yokudlulisa ukuze kunxeshezelwe ukuvala, thuthukisa ukusebenza kokuvalwa kwe-valve uvemvane futhi andise izinzuzo zokuphila kwesevisi.

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.

Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,Ivalve yesango,Hlola Valve,I-Globe Vavlve,I-Y-Strainers,I-Acurator kagesi,Ama-Acurator Womoya.
