Ukuqinisekisa ukuvalwa kohlelo lwamapayipi e-valve, ngaphezu kokukhetha izinto zokuvala ezifanele, kuyadingeka futhi ukufaka i-gasket ngendlela efanele elandelayo:
I-gasket kumele ibekwe phakathi kwe-flange, okubaluleke kakhulu kuma-flange amahlombe; ukuqinisekisa ukuthi indawo yokuvala ithambile futhi inembile; ama-bolt axhumanisayo kumele aqiniswe ngokulinganayo nangokulinganayo; ukusetshenziswa kwama-washer ensimbi kumele kuqinisekiswe ukuthi umthwalo uyafana futhi uqinile. Sebenzisa i-torque wrench lapho ubopha; hlola futhi ulinganise kabusha i-torque ye-bolt exhumanisayo ngemva kokuba uhlelo lwe-valve piping lusebenze umjikelezo owodwa; ukuqinisekisa ukuthi impilo ye-gasket iyasebenza, sicela ungasebenzisi ama-anti-sticking agents noma ama-lubricant e-liquid noma e-metal matrix.

INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.

Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,I-Valve yeSango,Hlola i-Valve,I-Globe Vavlve,Izihlungi ze-Y,I-Acurator kagesi,Ama-Acurators omoya.
