Butterfly Valves

Neles butterfly valves include multiple series designed for different structural configurations and selection requirements. The Neldisc series, including L1/L2, L12, and L6/LW/LG, uses a triple-offset metal-seated design. The BO series uses a soft-seated, single-offset design, while the BW and BWX series use a double-offset metal-seated design. For specific applications, the BH series is designed for inlet isolation in air separation units, the BN series provides a full-bore solution for oxygen and industrial gases, and the BWX series focuses on low-temperature applications. When selecting a valve, users should pay particular attention to the sealing requirements for the specific isolation, control, and high-frequency cycling conditions.
