The Fisher Type 3590 is an electro-pneumatic (I/P) valve positioner typically used to convert a milliampere (mA) DC input signal into a proportional pneumatic output pressure to position a control valve.

Because the 3590 is largely considered an obsolete product, new printed manuals are no longer manufactured, but digital technical guides remain available for maintenance and calibration. Technical Specifications Description Input Signal 4-20 mA DC (standard), 10-50 mA, or Split Range Internal Resistance Output Signal

Pneumatic pressure for valve plug travel (7/16 to 4-1/8 inch) Supply Pressure 5 PSIG higher than upper range limit of input; Max 50 PSI Action Field-reversible (Direct or Reverse) Operating Temp -40°F to 150°F (-40°C to 66°C) Installation & Maintenance Summary

Mounting: Usually requires a specific mounting bracket and stainless steel tag for identification.

Safety: Ensure all vent openings are clear before and during use to prevent pressure buildup within the housing.

Qualified Personnel: Maintenance should only be performed by trained technicians. You must isolate the control valve from process pressure and drain media before servicing.

Calibration Check: If the unit is ordered separately from the actuator, field alignment and calibration are required before service. Manual Resources

You can access the legacy documentation and supplemental instructions through these specialized archives: Type 3590 Supplemental Instructions (PDF) via Scribd. Technical Product Data from Stewart Instrument.

General Fisher instruction manual catalogs often include 3590 details under the "Transducers and Valve Positioners" section.

Maintenance

Regularly inspect air filters and replace as needed.
Check tubing and fittings for leaks annually or per schedule.
Calibrate zero/span after major maintenance or actuator replacement.
Keep enclosure sealed against moisture; replace gaskets if degraded.
Lubricate linkage per actuator manufacturer recommendations.

Step 2 – Zero Adjustment

Apply minimum input signal (e.g., 3 psi).
Loosen the lock nut on the zero adjustment screw.
Turn the screw to move the flapper until the actuator just begins to move the valve from its seat.
For spring-return actuators, set the valve exactly at its closed position.
