NSEN tau tsim muaj xyoo 1983, tshwj xeeb hauv thaj teb 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
• Kev tiv thaiv hluav taws kub siab npauj npaim valve
• Lub valve damper
• Lub valve uas tiv taus dej hiav txwv

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