BASIC INFO
Emerson Fisher 3582i Electro-pneumatic valve positioner 100% original brand new
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.
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.
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.
