The Flowserve Logix 3800 Digital Positioner is a high-performance, HART 7-enabled smart positioner designed for precise control of rotary and linear valves in demanding process environments. Featuring advanced diagnostics, auto-tuning, and a robust aluminum housing with IP66/NEMA 4X protection, it ensures reliable operation with ±0.5% full-scale accuracy. The intuitive local interface with LCD display and push buttons simplifies commissioning, while real-time data on valve signature, friction, and response time supports predictive maintenance. Ideal for chemical processing, oil & gas, and power generation, the Logix 3800 integrates seamlessly with DCS via HART, FOUNDATION Fieldbus, or Profibus PA for optimized plant performance and reduced downtime.
