Product Description
The SRD991-CHFS7FAANY-CSV14 is a smart digital valve positioner for Foxboro I/A Series and Evo DCS. It provides precise control of pneumatic actuators with advanced HART communication for remote diagnostics, configuration, and real-time valve monitoring.
Featuring a double-acting pneumatic amplifier, multi-lingual graphical LCD, and local push-buttons, this positioner supports auto-start self-calibration and manual adjustments directly at the valve. Its copper-free construction makes it ideal for chemical processes where contamination must be avoided.
