Kuti muwonetsetse kuti makina opayikira ma valve atsekedwa, kuwonjezera pa kusankha zipangizo zoyenera zopayikira, ndikofunikiranso kuyika gasket motere:
Gasket iyenera kuyikidwa pakati pa flange, zomwe ndizofunikira kwambiri pa ma flange a mapewa; kuti zitsimikizire kuti pamwamba pake pali kusalala komanso kulondola kogwirira ntchito; mabolt olumikizira ayenera kukhala olimba mofanana komanso mofanana; kugwiritsa ntchito ma washer achitsulo kuyenera kuonetsetsa kuti katunduyo ndi wofanana komanso wolimba. Gwiritsani ntchito wrench ya torque mukayiyika; yang'anani ndikuyikanso torque ya bolt yolumikizira pambuyo poti makina a valve agwira ntchito kwa nthawi imodzi; kuti muwonetsetse kuti gasket ikugwira ntchito nthawi yayitali, chonde musagwiritse ntchito mafuta oletsa kumatira amadzimadzi kapena achitsulo.

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