Fisher 3582i Electropneumatic Converter Valve Positioner
Description of Fisher 3582i Electropneumatic Converter Valve Positioner 582i Valve Positioner
• The FS 3582i is a field-proven positioner which is accurate, fast-responding, and able to withstand the vibrations of most plant environments. Low steady-state air consumption contributes to efficient operation.
• The Fisher 3582i pneumatic valve positioner is used with diaphragm-actuated, sliding-stem control valve assemblies.
• The 3582i electro-pneumatic positioner, is a modular unit that can be installed at the factory or in the field. The converter receives a DC current input signal and
provides a proportional pneumatic output signal eliminating the need for a seperate i/p in the field.
• This positioner consists of a Fisher 582i electro-pneumatic converter installed on a 3582 pneumatic valve positioner. The 3582i provides an accurate valve stem position that is proportional to a DC current input signal.
The 582i electro-pneumatic converter is a modular unit that can be installed at the factory or in the field. The converter receives a DC current input signal and provides a proportional pneumatic output signal through a nozzle/flapper arrangement. The pneumatic output signal provides the input signal to the pneumatic positioner, eliminating the need for a remote mounted transducer.

Max Input Bellows Pressure 2.4 bar
Fisher 3582 pneumatic, single-acting positioner is used with diaphragm-actuated, sliding-stem control valve assemblies. The pneumatic valve positioner receives a pneumatic input signal from a control device and modulates the supply pressure to the control valve actuator, providing an accurate valve stem position that is proportional to the pneumatic input signal.
The Type 3582i electro-pneumatic valve positioner consists of a Type 582i electro-pneumatic converter installed on a Type 3582 pneumatic valve positioner.The Type 3582i provides an accurate valve stem position that is proportional to a dc current input ignal.
The Type 582i electro-pneumatic converter, shown in figure 5, is a modular unit that can be installed at the factory or in the field (2). The converter receives a dccurrent input signal and provides a proportional pneumatic output signal through a nozzle/flapper arrangement. The pneumatic output signal provides the input signal to the pneumatic positioner,eliminating the need for a remote mounted transducer.

Features of Fisher 3582i Electropneumatic Converter Valve Positioner 582i Valve Positioner
• The range of the adjustable zero and span permits the use of all standard input signals including split ranges.
• Because units from one positioner family can be used in a variety of control applications, basic spare parts inventory requirements are simplified and fewer spare parts are needed to support a plant-wide positioner applications base.
• With the cover removed, zero and span adjustments are easily accessible and can be made with a screw driver and spanner.
• Changes in supply pressure and valve load have minimal effect on positioner operation.
• Case, components, and gasket materials withstand harsh environments. Positioner bleed air purges internal parts for additional protection.
• Simple adjustments permit switching between direct and reverse action.
• To support diagnostic testing of valve/actuator/positioner packages with the FlowScanner™ valve diagnostic system, connectors, piping, and other hardware can be installed between the positioner and the actuator.
