NSEN tau tsim muaj nyob rau xyoo 1983, tshwj xeeb hauv thaj chaw ntawm eccentric npauj npaim li qub.Tom qab xyoo ntawm kev tshawb nrhiav thiab kev xyaum, cov khoom lag luam uas twb muaj lawm hauv qab no tau tsim:

• Triple eccentric npauj npaim valve
• Kev ua haujlwm siab npauj npaim valve
• Hlau rau hlau npauj npaim valve
• -196 ℃ Cryogenic npauj npaim valve
• Kub kub tiv thaiv npauj npaim valve
• Damper npauj npaim valve
• Seawater resistant npauj npaim valve

Hauv kev tshaj lij, tsom mus rau npauj npaim li qub.NSEN tseem niaj hnub txhim kho nws tus kheej kev tsim nyog thiab ua pov thawj nws lub zog.
