The field-proven positioner for accurate valve control in tough conditions
The Fisher 3582i is an electro-pneumatic valve positioner that consists of a 582i converter mounted on a 3582 pneumatic base. It takes a 4-20 mA input signal and provides precise pneumatic output to the actuator. Many plants use it on diaphragm-actuated sliding-stem valves because it's accurate, responds quickly, and handles vibration well.
