Ukuqinisekisa ukuvalwa kwesistimu yamapayipi e-valve, ngaphezu kokukhetha izinto ezifanele zokuvala, kuyadingeka futhi ukufaka i-gasket ngendlela elandelayo efanele:
I-gasket kufanele ibekwe phakathi nendawo ye-flange, ebaluleke kakhulu kuma-flange ehlombe;ukuqinisekisa ukucaba kanye nokunemba kokucubungula kwendawo yokuvala;ama-bolts okuxhuma kufanele ahlanganiswe ngokulinganayo futhi aqiniswe ngokulinganayo;ukusetshenziswa kwama-washers ensimbi kufanele kuqinisekise ukuthi umthwalo ufana futhi uqinile Sebenzisa isikrufu se-torque lapho ubopha;hlola futhi ulinganise kabusha i-torque yebhawodi yokuxhuma ngemuva kokuthi uhlelo lwamapayipi e-valve lusebenze umjikelezo owodwa;ukuze uqinisekise impilo yesevisi ye-gasket, sicela ungasebenzisi ama-anti-sticking agents noma izinto zokugcoba ze-matrix ye-liquid noma yensimbi.

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.

Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,Ivalve yesango,Hlola Valve,I-Globe Vavlve,I-Y-Strainers,I-Acurator kagesi,Ama-Acurator Womoya.
