3.1 Mtundu
Valavu yagulugufe ili ndi mawonekedwe osiyanasiyana monga eccentric imodzi, mtundu wa mbale yokhazikika, mtundu wapakati, eccentric iwiri ndi eccentric katatu.Kuthamanga kwapakati kumagwira pa shaft ya valve ndikudutsa mu mbale ya butterfly.Choncho, pamene otaya kukana kuthamanga kwambiri ndi m'mimba mwake yaing'ono ndi lalikulu, m'mimba mwake kutsinde ndi makulidwe a gulugufe mbale adzawonjezeka moyenerera.Ngati ma valve a zipata, ma valve a mpira kapena ma valve a globe amagwiritsidwa ntchito, kuchokera kuzinthu zosindikizira ndi kukana kutuluka Kusanthula kuli koyenera kuposa valavu ya butterfly.

M'zaka zaposachedwa, kutuluka kwa ma valve otsekemera otsekemera m'madzi kwapangitsa kuti zofooka za ma valve a zitseko zikhale zosavuta kuziyika.Kukana kwake koyenda kumakhala kochepa, ndipo kumatha kukonzedwa pa intaneti.Ndiwoyenera kwambiri kwa madiresi ang'onoang'ono ndi apakatikati, choncho pang'onopang'ono wagwiritsidwa ntchito.
3.2 Kusindikiza awiri
Ubwino waukulu wa zitsulo zosindikizira agulugufe valavu ndi kusindikiza kodalirika, moyo wautali, kukana kutentha kwapamwamba, kosavuta kuwononga ndi kung'amba, komanso kuthamanga kwakukulu.Chifukwa chake, yakhala ikugwiritsidwa ntchito kwambiri m'zaka zaposachedwa, makamaka pazinthu zazikulu zamakina aukadaulo.Ngati valavu ya gulugufe yofewa ya mphira idapangidwa bwino ndikupangidwa, imatha kusindikizidwa bwino, ndipo mainchesi akulu amatha kusinthidwa mosavuta pa intaneti.Komabe, mphira imakhala ndi mavuto okalamba ndipo ingagwiritsidwe ntchito pokhapokha ngati kutentha sikukwera, choncho imagwiritsidwa ntchito kwambiri m'madzi a pampopi ndi madzi.

Ma valve agulugufe osindikizira zitsulo zakunja amagwiritsidwanso ntchito popopera, ma condensers, machitidwe ochotsera nthunzi ndi machitidwe osinthanitsa kutentha m'mafakitale amagetsi otentha.Zomera zamagetsi za nyukiliya zimagwiritsidwanso ntchito pakudzipatula kwa zipolopolo zokakamiza, makina opopera ndi brine, ndi zina zambiri, kudzipatula kusungirako mafuta ndi nthunzi mumayendedwe oyenga mafuta.Supply valve, desulfurization system ndi chithandizo cha gasi wamchira, kuphulika kwamafuta ndi gawo lothandizira.Palinso zomera za petrochemical, cryogenic, slurry and papermaking systems.
Kwa kutentha kwapakati komanso kupanikizika kwapakati, ndi bwino kugwiritsa ntchito mavavu agulugufe osindikiza zitsulo.Kwa malo omwe amafunikira kudalirika kwakukulu, moyo wautali, ndi kusintha kwa nthawi yaitali, ma valve agulugufe osindikizidwa ndi zitsulo ayenera kugwiritsidwanso ntchito.
Kwa valavu yomwe imagwiritsidwa ntchito pamadzi otentha otentha, ngati siwovuta kwambiri, sichidzasinthidwa kwa nthawi yaitali kapena kumene kuli kovuta kusintha, ndibwino kuti mutenge valve ya butterfly yokhala ndi chisindikizo chofewa.Ngati mtundu wa labala ungakhale wotsimikizika, mavavu agulugufe okhala ndi m'mimba mwake amadzi ayenera kukhala mavavu agulugufe okhala ndi mphira.

Kutuluka kosalekeza kwa umisiri watsopano ndi zipangizo zatsopano zidzapititsa patsogolo kayendetsedwe ka kayendetsedwe ka gulugufe, kukulitsa kagwiritsidwe ntchito ka valavu ya gulugufe, ndikuyika patsogolo zofunikira zosinthidwa pakupanga ndi kusankha valavu ya butterfly.

Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
