Fisher 3590 is a legacy electro-pneumatic valve positioner designed to provide precise throttling for control valves by converting an electrical input signal (typically 4-20 mA) into a proportional pneumatic output pressure. Stewart Instrument Although now classified as an obsolete product , technical support and instruction manuals remain essential for maintaining existing units. Key Specifications Input Signal: Standard 4-20 mA or 10-50 mA DC; supports split range. Output Signal: Emerson Electric Co

The Fisher 3590 is an electro-pneumatic valve positioner designed to receive a DC current input signal (typically 4-20 mA) and convert it into a proportional pneumatic output pressure to control a valve actuator. It is often used to ensure a linear relationship between the control signal and the actual valve position while overcoming friction and process force imbalances.
