Neles Series L1 and L2 Butterfly Valve for Accurate Flow

Neles™ Butterfly Valve, Series L1 and L2, is a high-performance triple eccentric valve. The Neldisc Series L1 and L2 triple eccentric disc 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

  • l1 wafer type, l2 lug type.
  • tripple offset, 2 piece shaft design.
  • one piece, full metal sealing without any resilient parts in pipeline.
  • high, long lasting tightness does not rely on differential pressure.
  • 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 – same spares can be used in multiple neles neldisc designs.
  • minimized actuator torque. smaller actuator and lower piping stress.
  • neldisc triple eccentric disc valves operate both in control and shut-off applications.
  • compact and light weight construction with neles b-series actuator.
  • suitable for vacuum service.
  • very tight even in low dp’s.
  • extended rangeability to 90 degrees control applications.
  • in-built thermal and pressure compensation.
  • optimized spare part inventory.
  • suitable to dirty and abrasive services.
