The Fisher 3560 series (primarily including the 3560V and 3560C models) is a pneumatic, force-balanced positioner used with both sliding-stem and rotary actuators. It continuously compares the input signal from a control device against the actual position of the valve stem. If a discrepancy exists, the positioner adjusts the pneumatic output pressure to the actuator until the correct position is achieved. Core Specifications

"Valve fails to stroke?" The manual provides a flow chart to check nozzle back-pressure and flapper alignment. "Hunting at mid-travel?" The manual guides you on tightening the range spring.

The Fisher 3560 balances a bellows force against a feedback spring force. Adjusting these forces aligns the physical valve stroke with your pneumatic signal. Step 1: Zero Adjustment Fisher 3560 Valve Positioner Manual Pdf

Easily field-reversible between direct-acting (increasing input increases output) and reverse-acting (increasing input decreases output).

Standard construction handles -40°C to 82°C (-40°F to 180°F). High-temperature options extend this range.

Before calibrating, you must first mount the positioner onto your Fisher valve actuator. This will vary based on your specific actuator model and configuration. The process generally involves:

– Apply the minimum input signal (e.g., 3 psig). Adjust the nozzle position until the valve stem just begins to move from its starting point. Designed to withstand high vibration and harsh process

While this article provides an exhaustive operational overview, keeping the official engineering documentation on hand is essential for exact part numbers, torque specifications, and cross-sectional diagrams.

This section outlines the specific models covered and the scope of the manual. It defines the parameters for which the positioner is designed, ensuring operators don't attempt to use the device outside of its intended pressure or temperature ranges. 2. Specifications

The Fisher 3560 is a robust, high-performance positioner. Unlike its digital counterparts (like the FIELDVUE series), the 3560 is an analog, pneumatic positioner known for its simplicity and durability. However, its mechanical linkages, cams, flapper valves, and nozzle assemblies require precise calibration.

Secure all mounting bolts to the torque specifications listed in the manual. 3. Calibration Instructions The Fisher 3560 series (primarily including the 3560V

cover pneumatic models with similar mechanical feedback and relay systems used in many Fisher valve assemblies. Actuator Support

The Fisher 3560 series includes pneumatic positioners that use a force-balance principle to provide precise, fast-acting control of pneumatic actuators. They are primarily paired with sliding-stem control valves but can be adapted for specific rotary applications depending on the mounting configuration. Key Models within the Series:
