Fisher specifications 3582 Pneumatic Positioner
Industrial Valves and Valve Equipment
Fisher® 3582 pneumatic, single-acting positioners are used with diaphragm driven, sliding-rod control valve assemblies. Pneumatic valve positioners receive pneumatic input signals from the control device and modulate supply pressure to the control valve actuators, providing accurate position valve rods that are comparable to pneumatic input signals.
Versatile Modular Design-3582 positioners can be upgraded in the field to electro-pneumatic 3582i by replacing the measuring block with 582i electro-pneumatic converter assembly. Assembly converters attach to case positioners, providing cost-effective conversions. Thus, in the field, 3582 positioners can be upgraded from pneumatics to electronics to match new control strategies.
