4. Mphamvu yokwezera ndi mphindi yokwezera:

Mphamvu yotsegulira ndi kutseka ndi mphamvu yotsegulira ndi kutseka imatanthauza mphamvu kapena mphindi yomwe iyenera kugwiritsidwa ntchito potsegula kapena kutseka valavu. Mukatseka valavu, ndikofunikira kupanga mphamvu inayake yotseka pakati pa magawo otsegulira ndi kutseka ndi malo awiri otsekera a mpando, ndipo nthawi yomweyo muthane ndi mpata pakati pa tsinde la valavu ndi kulongedza, ulusi pakati pa tsinde la valavu ndi nati, ndi chithandizo kumapeto kwa tsinde la valavu. Chifukwa chake, mphamvu yotseka ya magawo ena iyenera kugwiritsidwa ntchito. Pakutsegula ndi kutseka kwa valavu, mphamvu yotsegulira ndi kutseka yofunikira imasinthidwa, ndipo mtengo wake waukulu ndi pamene phosphorous yomaliza yatsekedwa kapena mphindi yoyamba yotsegulira. Mukapanga ndi kupanga mavalavu, yesetsani kuchepetsa mphamvu yawo yotseka ndi mphamvu yotseka.
5. Liwiro lotsegulira ndi kutseka:
Liwiro lotsegulira ndi kutseka limafotokozedwa ndi nthawi yomwe imafunika kuti valavu itsirize kutsegula kapena kutseka. Nthawi zambiri, palibe zofunikira zokhwima pa liwiro lotsegulira ndi kutseka la valavu, koma mikhalidwe ina yogwirira ntchito imakhala ndi zofunikira zapadera pa liwiro lotsegulira ndi kutseka. Ngati zina zimafuna kutsegula kapena kutseka mwachangu kuti zipewe ngozi, zina zimafuna kutseka pang'onopang'ono kuti zipewe nyundo yamadzi, ndi zina zotero. Izi ziyenera kuganiziridwa posankha mtundu wa valavu.
6. Kuzindikira ndi kudalirika pa zochita:
Izi zikutanthauza kukhudzidwa kwa valavu poyankha kusintha kwa magawo a media. Kwa mavavu okhala ndi ntchito zinazake monga mavavu opindika, mavavu ochepetsa kupanikizika, ndi mavavu owongolera, komanso mavavu okhala ndi ntchito zinazake monga mavavu oteteza ndi mipiringidzo, kukhudzidwa kwawo ndi kudalirika ndizofunikira kwambiri pakugwira ntchito kwaukadaulo.
7. Nthawi yotumikira:
Zimasonyeza kulimba kwa valavu, ndi chizindikiro chofunikira cha magwiridwe antchito a valavu, ndipo zili ndi kufunika kwakukulu pazachuma. Nthawi zambiri zimafotokozedwa potengera kuchuluka kwa malo otseguka ndi otseka omwe angatsimikizire zofunikira pakutseka, ndipo zimathanso kufotokozedwa potengera nthawi yogwiritsira ntchito.

Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
