Fisherr 3582 and 3582i Positioners and 582i

Electro-Pneumatic Converter

Fisher 3582 pneumatic valve positioners and 3582i

electro-pneumatic valve positioners, shown in figure 1,

are used with diaphragm-actuated, sliding-stem

control valve assemblies. The pneumatic valve

positioners receive a pneumatic input signal from a

control device and modulate the supply pressure to

the control valve actuator, providing an accurate valve

stem position that is proportional to the pneumatic

input signal.

3582NS positioners are designed for nuclear power

applications. The 3582NS construction includes

materials that provide superior performance at

elevated temperature and radiation levels. The O-rings

are EPDM (ethylene propylene) and the diaphragms

are EPDM/meta-aramid. EPDM demonstrates superior

temperature capability and shelf life over nitrile.

Note

Use a clean, dry, oil-free air supply with instruments

containing EPDM components. EPDM is subject to

degradation when exposed to petroleum-based lubricants.

The meta-aramid diaphragm fabric demonstrates

improved strength retention at elevated temperature

and radiation conditions.

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 electro-pneumatic valve 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.

FISHER 3582 PNEUMATIC

VALVE POSITIONER

The 582i electro-pneumatic converter, shown in figure

3, 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.

Note

Upgrading an existing 3582 positioner by field installation of

a 582i electro-pneumatic converter may require changing

the existing positioner mounting and the input signal range.

Contact your Emerson Process Management sales office

when planning an upgrade.
