8. Features

  1. Precise Flow Control
    Globe valve design provides excellent throttling capability with linear or equal percentage flow characteristics, suitable for regulating applications.

  2. Electric Actuation
    Enables remote operation, automation, and integration into DCS/PLC systems. Modulating version supports continuous process control.

  3. Reliable Shut‑off
    Soft seat option provides bubble‑tight shut‑off; metal seat option offers durability for high‑temperature or abrasive media.

  4. Robust Construction
    Rugged bolted bonnet design ensures long service life and ease of maintenance.

  5. Manual Override
    Handwheel allows manual operation during power failure or commissioning.

  6. Versatile Material Options
    Body materials available in carbon steel (WCB) for general service, or stainless steel (CF8/CF8M) for corrosive environments.

  7. Stem Seal Integrity
    PTFE or flexible graphite packing provides reliable stem sealing with low friction and long cycle life.
