Neles Series L6, LW, and LG Butterfly Valve for Versatility

Neles™ Butterfly Valve, Series L6, LW, and LG, are part of the Neldisc™ high-performance triple eccentric disc valve series. These valves are designed for both control and shut-off applications, offering close to equal percentage characteristics and superior tightness.

Benefits

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.

Features

l6 double flanged, 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 q-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.
