- Funkce
- Precise Flow Control
Globe valve design provides excellent throttling capability with linear or equal percentage flow characteristics, suitable for regulating applications. - Electric Actuation
Enables remote operation, automation, and integration into DCS/PLC systems. Modulating version supports continuous process control. - Reliable Shut‑off
Soft seat option provides bubble‑tight shut‑off; metal seat option offers durability for high‑temperature or abrasive media. - Robust Construction
Rugged bolted bonnet design ensures long service life and ease of maintenance. - Manual Override
Handwheel allows manual operation during power failure or commissioning. - Versatile Material Options
Body materials available in carbon steel (WCB) for general service, or stainless steel (CF8/CF8M) for corrosive environments. - Stem Seal Integrity
PTFE or flexible graphite packing provides reliable stem sealing with low friction and long cycle life.
