The 3590 series typically includes the standard , 3590S , and 3590ST models. Input Signal: 4 to 20 mA DC. Internal Resistance: Approximately 300 Ohms. Supply Pressure: Maximum 50 psig.

For rotary valves (e.g., Fisher Vee-Ball), you must use a rotary cam and adjust the feedback arm length according to the specific angle of rotation (typically 90°).

The primary instruction manual for this series is typically found under historical Fisher documentation. Archival Access: You can view or download the manual on the Scribd Archive for Fisher 3590 Alternative Support:

50 PSI maximum; should be 5 PSIG higher than the upper range limit of the input signal. Temperature Limits: -40°F to 150°F (-40°C to 66°C). Action: Direct or reverse acting. ⚠️ Safety Precautions

Always verify the actuator type (diaphragm, piston, spring-return) and required output action before mounting. The manual provides separate piping diagrams for double-acting and single-acting actuators.
