The Flowserve Positioner Logix 3800 digital positioner features a modular design for flexible mounting. It can control both double-acting and single-acting valves with minimal air consumption. Its versatility allows for direct mounting to VDI/DE standards without additional tubing.
Features of Digital Positioners – Logix 3800
- Up to 80% more air capacity with minimal air consumption
- Robust, reliable, safe, non-incendive, and explosion-proof design
- Easy configuration and calibration
- Predictive diagnostics
