1. Nthawi zambiri, pakuwongolera, kuwongolera ndi matope, kapangidwe kake kamayenera kukhala kakang'ono m'litali komanso mwachangu pakutsegula ndi kutseka liwiro (1/4 revolution).Kutsika kwapakati (kusiyana kwapang'onopang'ono), valavu ya butterfly ndiyofunikira.
2. Valavu ya butterfly ingagwiritsidwe ntchito pamene kusintha kwa malo awiri, njira yopapatiza, phokoso lochepa, cavitation ndi vaporization, pang'ono kutayikira mumlengalenga, ndi abrasive media.
3. Pamene valavu ya butterfly imagwiritsidwa ntchito pazikhalidwe zapadera monga kusintha kwa throttling, kusindikiza mwamphamvu, kapena kuvala kwambiri, kutentha kochepa (cryogenic), etc., m'pofunika kugwiritsa ntchito chisindikizo chachitsulo chopangidwa mwapadera ndi katatu-eccentric kapena kawiri- eccentric chosinthira valavu Odzipereka agulugufe pansi.
4. The centerline butterfly valve ndi yoyenera madzi abwino, zimbudzi, madzi a m'nyanja, madzi amchere, nthunzi, gasi lachilengedwe, chakudya, mankhwala, ndi mafuta omwe amafunikira kusindikiza kwathunthu, kutayikira kwa zero kuyesa gasi, zofunikira pa moyo wapamwamba, ndi kutentha kwa ntchito - - 10 ℃ ~ 150 ℃.Ndipo mitundu yosiyanasiyana ya asidi ndi alkali ndi mapaipi ena.
5. Vavu yagulugufe yotsekedwa yofewa ndiyoyenera kutsegula ndi kutseka njira ziwiri ndikusintha mpweya wabwino ndi kuchotsa fumbi mapaipi.Amagwiritsidwa ntchito kwambiri m'mapaipi a gasi ndi njira zamadzi muzitsulo, mafakitale opepuka, mphamvu zamagetsi, ndi machitidwe a petrochemical.
6. Chitsulo chachitsulo chachitsulo chosindikizira chachiwiri cha butterfly eccentric ndi choyenera kutentha kwa m'tawuni, gasi, madzi ndi mpweya wina, mafuta, asidi ndi mapaipi a alkali, monga chipangizo chowongolera ndi chogwedeza.
7. Kuphatikiza pa kugwiritsidwa ntchito ngati valavu yayikulu yolumikizira mpweya (PSA) kupatukana kwa pulogalamu yamagetsi, valavu yagulugufe yachitsulo-to-zitsulo ingagwiritsidwenso ntchito kwambiri mumafuta, petrochemical, chemical, metallurgical, magetsi ndi minda ina.Ndi valavu yachipata ndi valve yoyimitsa.Chinthu china chabwino.
Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
