Neles™ butterfly valve, series L6
Neldisc™ high performance triple eccentric valves
Neles Neldisc series L6 triple eccentric disc valve operate both in control and shut-off applications, with close to equal percentage characteristics and superior tightness.
Minimized pressure loss and
energy costs of the process
Industry best valve capacity
Consistent performance
even in the most difficult,
changing process
conditions
Shortest possible
maintenance hours
- Triple offset
- Driveshaft with trunnion or through shaft (Model D only)
- Zero leakage with true metal-to-metal sealing
