3582, 582i, and 3583
January 2013
Description (continued)
Under the 10CFR50, Appendix B, quality assurance program, the 3582NS positioner is qualified commercial grade
dedicated. These can be supplied as 10CFR, Part 21 items.
The 3582i is an electro‐pneumatic valve positioner, consisting of a 582i electro‐pneumatic converter installed on a
3582 pneumatic valve positioner. The 3582i valve positioner 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. However, do
not install a 582i converter on an existing positioner until you contact your Emerson Process Management sales office
for application assistance.
The 582i converter receives the DC current input signal and, through a nozzle/flapper arrangement, provides a
proportional pneumatic output signal. This pneumatic output signal provides the input signal to the pneumatic valve
positioner, eliminating the need for a remote‐mounted transducer.
3583 pneumatic valve stem position transmitters are for use with sliding‐stem diaphragm actuators. These units
provide an output signal that is directly proportional to the valve stem position.
Refer to the type number description for a detailed explanation of type numbers.

Type Number Descriptions

The following descriptions provide specific information on the different valve positioner or valve stem position
transmitter constructions. If the type number is not known, refer to the nameplate on the positioner. For the location
of the nameplate, refer to key 25 in figure 21.
3582—Pneumatic valve positioner with bypass and instrument, supply, and output pressure gauges.
3582A—Pneumatic valve positioner without bypass and without pressure gauges.
3582C—Pneumatic valve positioner without bypass and with automotive tire valves instead of pressure gauges.
3582D—Pneumatic valve positioner with bypass and with automotive tire valves instead of pressure gauges.
3582G—Pneumatic valve positioner without bypass and with instrument, supply, and output pressure gauges.
3582NS—Pneumatic valve positioner for nuclear service applications with or without bypass and with automotive tire
valves instead of pressure gauges.
3582i—Electro‐pneumatic valve positioner without bypass; with 582i converter; and with: supply and output pressure
gauges, automotive tire valves, or pipe plugs.
582i—Electro‐pneumatic converter with: supply and output pressure gauges, automotive tire valves, or pipe plugs.
Used for conversion of a 4‐20 mA input signal to a 0.2 to 1.0 bar (3 to 15 psig) input signal for the pneumatic valve
positioner.
3583—Pneumatic valve stem position transmitter with supply and output pressure gauges.
3583C—Similar to the 3583 valve stem position transmitter except with automotive tire valves in place of pressure
gauges.
