Factory OEM Customized Pneumatic Diaphragm Control Valves Fisher Emerson 3582 3582i DVC2000 DVC6200 Valve Controller

The Fisher 3582i is a classic electro-pneumatic valve positioner that converts a 4–20 mA DC input signal into proportional pneumatic output for pneumatic actuators. It consists of a 582i converter mounted on a 3582 pneumatic positioner base. It is simple, reliable, and widely used on sliding-stem control valves in plants that still prefer traditional analog positioners with good vibration resistance and straightforward setup.
