Valve ya mpira imatha kutsekedwa mwamphamvu ndi kuzungulira kwa digirii 90 ndi torque yaying'ono.Chingwe chofananira chamkati cha valve chimapereka njira yowongoka yowongoka ndi kukana pang'ono kwapakati.Kawirikawiri amaonedwa kuti valavu ya mpira ndi yoyenera kwambiri kutsegulira ndi kutseka mwachindunji, koma zomwe zachitika posachedwa zapanga valavu ya mpira kuti iwonongeke ndikuwongolera kutuluka.Mbali yaikulu ya valavu ya mpira ndi dongosolo lake yaying'ono, ntchito yosavuta ndi kukonza, oyenera atolankhani ambiri ntchito monga madzi, zosungunulira, asidi ndi gasi, komanso oyenera TV ndi zinthu zovuta ntchito, monga mpweya, hydrogen peroxide, ethylene ndi methane.Thupi la valve ya mpira likhoza kukhala lophatikizana kapena lophatikizidwa.
Evolution ndi mfundo ntchito
Vavu ya mpira idasinthika kuchokera ku valavu ya pulagi.Ili ndi ntchito yokweza yofanana yozungulira madigiri a 90, koma kusiyana kwake ndikuti thupi la tambala ndi gawo lomwe lili ndi zozungulira podutsa dzenje kapena njira yodutsa mumzere wake.Chiŵerengero cha gawo ndi kutsegulidwa kwa tchanelo chiyenera kukhala kotero kuti pamene gawolo likuzungulira madigiri 90, mabwalo onse ayenera kuwonekera pakhomo ndi kutuluka, motero kudula kutuluka.
Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
