Isungulwe ngo-2000, i-NAI-LOK izenzele igama ohlwini lwabahlinzeki abaphambili base-China. Sigxila ekukhiqizeni, ocwaningweni nasekuthuthukisweni, ekuthengisweni kwamavalvu ensimbi kanye namavavu ezimboni.Sineminyaka engaphezu kwengu-20 yokukhiqiza ama-valve anembayo kanye neminyaka eyi-10 yesipiliyoni sokuthumela ngaphandle.
Ukulawula kwethu okuqinile kanye nokuphathwa kwayo yonke inqubo yokukhiqiza kusenza sikwazi ukuhlinzeka ngemikhiqizo ehlangabezana nezimfuneko zamakhasimende ethu ngokuphepha komkhiqizo, ukusebenza nokuklama ngamanani ancintisanayo, kuyilapho siqinisekisa izikhathi zokuhola ezimfushane kakhulu emakethe.

Sinekhono lokukhiqiza nokuhlinzeka ngezigaba ezi-4 zemikhiqizo ehlukene, okuhlanganisa:
■ Amavalvu Amathuluzi Okujwayelekile Nokufakwa
■ Imikhiqizo Ehlanzekile Ephakeme kanye Nemikhiqizo Ehlanzekile Ephakeme- I-GPTECH UHP PRODUCTS
■ Ipayipi neshubhu
■ Special Alloy Valves


Silwela ukuthuthukisa, ukusebenzela amakhasimende omhlaba kanye nokuhlinzeka ngemikhiqizo ezinzile nethembekile.
