I-NSEN yasungulwa ngo-1983, igxile emkhakheni wama-eccentric butterfly valves.Ngemuva kweminyaka yokuhlola nokusebenza, uchungechunge lomkhiqizo olukhona ngezansi selwekhiwe:

• I-valve yevemvane eyi-eccentric kathathu
• Ukusebenza okuphezulu kwe-butterfly valve
• I-valve uvemvane yensimbi iye kweyensimbi
• -196 ℃ I-valve uvemvane lwe-Cryogenic
• I-valve yevemvane yokuvikela umlilo ngezinga eliphezulu lokushisa
• I-valve ye-butterfly ye-Damper
• I-valve yevemvane ekwazi ukumelana namanzi olwandle

Emkhakheni wobuchwepheshe, gxila kuma-butterfly valves.I-NSEN nayo ihlale izithuthukisa iziqu zayo futhi ifakazela amandla ayo.
