Intelligent Valve Positioning, Diagnostics and Asset Performance Monitoring
Digital valve controllers are microprocessor-based instruments that provide precise valve positioning, advanced diagnostics, and digital communication capabilities. Compatible with HART®, FOUNDATION™ Fieldbus, and PROFIBUS® communication protocols, they enable operators and maintenance teams to monitor valve performance, simplify commissioning, and improve plant reliability.
Unlike conventional positioners, digital valve controllers continuously monitor valve operation and provide actionable diagnostic data. This allows maintenance personnel to identify developing issues before they result in unplanned downtime or process disruption.
In-service diagnostics can help detect:
- Instrument air quality issues
- Air leaks and supply pressure restrictions
- Excessive valve friction
- Valve dead band
- Calibration drift
- Mechanical wear and performance degradation
Digital communication enables two-way access to valve and positioner information, making setup, calibration, and troubleshooting faster and more effective.
