3582i I/P Valve Positioner Electro Pneumatic Converter Sliding Stem Control Valve
The 3582i electro-pneumatic valve positioner provides accurate stem positioning for diaphragm-actuated sliding-stem control valves by converting a 4-20 mA electrical signal into a proportional pneumatic output. It consists of a 582i converter mounted on a 3582 pneumatic positioner body.
Designed for reliable performance in industrial environments, the 3582i supports both full-range and split-range operation. Action is field-reversible, and the unit offers straightforward integration with standard control systems. The modular converter design allows flexibility in configuration while maintaining consistent positioning accuracy.

Applied across process control environments such as chemical plants, refining, power facilities, and other industries that rely on precise modulation of sliding-stem control valves.
Typical concerns include matching the positioner to actuator characteristics or achieving stable response under varying process conditions. Proper supply pressure selection and calibration help ensure consistent performance.
Suitable as a replacement for earlier 3582 pneumatic units when an electro-pneumatic solution is required, or for comparable electro-pneumatic positioners on similar valve assemblies.
We offer authentic instruments with attention to technical compatibility and application support.
Standard lead time is 6-8 weeks.
