Neles™ butterfly valve, series L1 and L2

Features

• The L1 valve type is a wafer-based valve, while the L2 valve type is lug-based
• Both valve types feature a triple offset design and a two-piece shaft design
• The pipeline uses a one-piece, full metal sealing system without any resilient parts
• The valves boast high, long-lasting tightness that is not dependent on differential pressure
• The patented S-disc feature delivers unique, industry-leading valve control
• The modular design of the valves minimizes the inventory of spare parts, as the same spares can be used across multiple Neles Neldisc designs
• The minimized actuator torque allows for a smaller actuator and reduced piping stress
• The Neldisc triple eccentric disc valves can function in both control and shut-off applications
• The valves have a compact and lightweight construction with a Neles B-series actuator
• They are suitable for vacuum service and provide a tight seal even in low differential pressures
• The valves have an extended rangeability of up to 90 degrees for control applications
• They feature built-in thermal and pressure compensation
• The spare part inventory is optimized
• The valves are suitable for use in dirty and abrasive services
