(1) kapangidwe ka valve yapadziko lonse lapansi ndi yosavuta kuposa valavu yachipata, ndipo kupanga ndi kukonza ndikosavuta.
(2) Kusindikiza pamwamba sikophweka kuvala ndi kukanda, kusindikiza bwino, kutsegula ndi kutseka pakati pa valavu ya valve ndi valavu yosindikiza pamwamba popanda kutsetsereka kwachibale, kotero kuvala ndi kukanda sikuli kwakukulu, ntchito yabwino yosindikiza, moyo wautali wautumiki.
(3) potsegula ndi kutseka, chiwombankhanga cha disc ndi chaching'ono, kotero kutalika kwa valve yapadziko lonse ndi yaying'ono kuposa valve yachipata, koma kutalika kwa dongosololi ndi lalitali kuposa valve yachipata.
(4) Kutsegula ndi kutseka torque ndi yayikulu, kutsegula ndi kutseka kumangovuta, nthawi yotsegula ndi yotseka ndiyofunika kwambiri.
(5) kukana kwamadzimadzi ndi kwakukulu, chifukwa njira yapakatikati mu thupi la valve ndi yowawa, kukana kwamadzimadzi ndi kwakukulu komanso kugwiritsa ntchito mphamvu kwakukulu.
(6) pamene kuthamanga kwadzina Pn kumayendedwe apakati kumakhala kochepa kapena kofanana ndi 16Mpa, nthawi zambiri kumakhala pansi, ndipo sing'anga imachokera kumunsi kwa disc valve;Kuthamanga mwadzina Pn ≥ 20Mpa, kawirikawiri amagwiritsa ntchito countercurrent, otaya sing'anga kuchokera mbali ya chimbale.Kuonjezera mphamvu yosindikiza.Ikagwiritsidwa ntchito, sing'anga yodulira valavu imatha kuyenderera mbali imodzi ndipo singasinthe njira yolowera.
(7) ikatsegulidwa kwathunthu, diski nthawi zambiri imakokoloka.
Mzere wa tsinde la valve ya valavu yapadziko lonse lapansi ndi perpendicular kumtunda wosindikiza wa mpando wa valve.Stroke yotseguka / yotseka ndi yayifupi ndipo imakhala yodalirika kwambiri yodula, zomwe zimapangitsa kuti valavu iyi ikhale yoyenera kudulidwa kwapakatikati kapena kuwongolera ndi kugwedeza.

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

Zogulitsa zazikulu:Valve ya Butterfly,Valve ya Mpira,Chipata cha Chipata,Onani Vavu,Globe Vavlve,Y-Strainers,Electric Acurator,Pneumatic Acurators .
