4. Mphamvu yokwezera ndi mphindi yokwezera:

Kutsegula ndi kutseka mphamvu ndi kutsegula ndi kutseka torque kumatanthawuza mphamvu kapena mphindi yomwe iyenera kugwiritsidwa ntchito kutsegula kapena kutseka valve.Mukatseka valavu, ndikofunikira kupanga chisindikizo chapadera pakati pa magawo otsegulira ndi kutseka ndi malo awiri osindikizira a mpando, ndipo nthawi yomweyo kugonjetsa kusiyana pakati pa tsinde la valve ndi kulongedza, ulusi pakati pa tsinde la valve ndi nati, ndi chothandizira kumapeto kwa tsinde la valve.Mphamvu yothamanga ya mbali zina zotsutsana, motero, mphamvu yotseka ndi torque yotseka iyenera kugwiritsidwa ntchito.Panthawi yotsegulira ndi kutseka kwa valve, mphamvu yotsegula ndi yotseka yofunikira ndi kutsegula ndi kutseka torque imasinthidwa, ndipo mtengo wapamwamba ndi pamene phosphorous yomaliza yatsekedwa kapena Mphindi yoyamba yotsegula.Popanga ndi kupanga ma valve, yesetsani kuchepetsa mphamvu yawo yotseka ndi torque yotseka.
5. Kutsegula ndi kutseka liwiro:
Kuthamanga ndi kutsegula ndi kutseka kumasonyezedwa ndi nthawi yofunikira kuti valve imalize ntchito yotsegula kapena yotseka.Kawirikawiri, palibe zofunikira zokhwima pa kutsegula ndi kutseka kwa valve, koma zina zogwirira ntchito zimakhala ndi zofunikira zapadera pa kutsegula ndi kutseka liwiro.Ngati zina zimafuna kutsegula kapena kutseka mofulumira kuti ziteteze ngozi, zina zimafuna kutseka pang'onopang'ono kuteteza nyundo ya madzi, ndi zina zotero. Izi ziyenera kuganiziridwa posankha mtundu wa valve.
6. Kutengeka ndi kudalirika:
Izi zikutanthauza kukhudzika kwa valve poyankha kusintha kwa magawo a media.Kwa ma valve omwe ali ndi ntchito zenizeni monga ma throttle valves, ma valve ochepetsera kuthamanga, ndi ma valve oyendetsa, komanso ma valve omwe ali ndi ntchito zenizeni monga ma valve otetezera ndi misampha, kukhudzidwa kwawo ndi kudalirika ndizofunikira kwambiri zizindikiro za luso lamakono.
7. Moyo wautumiki:
Zimasonyeza kulimba kwa valve, ndilofunika kwambiri pa ntchito ya valve, ndipo ili ndi tanthauzo lalikulu lachuma.Nthawi zambiri amawonetsedwa potengera kuchuluka kwa kutsegulira ndi kutseka komwe kungathe kutsimikizira zofunikira zosindikizira, komanso kutha kuwonetsedwa potengera nthawi yogwiritsira ntchito.

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.
