Neles™ butterfly valve, series LW and LG
Neldisc™ high performance triple eccentric disc valves
Neles Neldisc series LW and LG triple eccentric disc valves 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
- LW wafer type, LG lug type
- Triple offset
- Driveshaft with trunnion or through shaft (Model D only)
- Zero leakage with true metal-to-metal sealing
- One piece, full metal sealing without any resilient parts in the pipeline
- High, long-lasting tightness
- Unique, industry best disc valve control behavior with patented S-disc feature – possible to mount even on existing valve units
- Modular design minimizes the spare part inventory – the same spares can be used in multiple Neles Neldisc designs
- Minimized actuator torque. Smaller actuator and lower piping stress
- BAM certified construction for gaseous oxygen as an option
- In-built thermal and pressure compensation
- Extended rangeability to 90 degrees control applications
- Optimized spare part inventory
- Suitable to dirty and abrasive services
