Introduction
Scope of Manual
This instruction manual includes installation, operation, calibration, maintenance, and parts ordering information for
Fisher 3582 pneumatic valve positioners, the 3582i electro‐pneumatic valve positioner, and 3583 pneumatic valve
stem position transmitters. Refer to separate instruction manuals for information on the control valve, actuator, and
accessories.
Do not install, operate or maintain a 3582 pneumatic valve positioner, a 3582i electro‐pneumatic valve positioner, or a
3583 pneumatic valve stem position transmitter without being fully trained and qualified in valve, actuator and
accessory installation, operation and maintenance.
To avoid personal injury or property damage it is important to
carefully read, understand, and follow all of the contents of this manual, including all safety cautions and warnings.
If
you have any questions about these instructions, contact your Emerson Process Management sales office before
proceeding.
Description
3582 pneumatic valve positioners and the 3582i electro‐pneumatic valve positioner 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. The positioner
adjusts the actuator supply pressure to maintain a valve stem position 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 fabric. EPDM demonstrates superior temperature capability
and shelf life over nitrile. The meta‐aramid diaphragm fabric demonstrates improved strength retention at elevated
temperature and radiation conditions.
CAUTION
Use a clean, dry, oil‐free air supply with instruments containing EPDM components. EPDM is subject to degradation when
exposed to petroleum‐based lubricants.
