The Fisher 3560 (often cited alongside similar legacy models like the 3582 or 3570) is a single-acting pneumatic positioner. It is typically used with diaphragm-actuated, sliding-stem control valve assemblies to modulate supply pressure and maintain a specific valve plug position. Key Technical Specifications

As the actuator stem moves, a feedback lever linked directly to the valve stem moves a feedback cam or spring. This action opposes the initial force exerted by the input bellows. Routine maintenance extends the operational lifespan of the

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:

The input signal (pneumatic pressure or electrical current converted to pressure via the I/P transducer) acts upon the input bellows or diaphragm matrix. The Fisher 3560 (often cited alongside similar legacy

Before mounting, verify that the positioner model matches the action of your actuator (Direct Acting vs. Reverse Acting). Inspect the feedback linkages for any signs of bending or thread damage during transit. Step-by-Step Mounting
