Fisher 3560 Valve Positioner Manual Pdf !!top!! May 2026
Standard nitrile O-rings and diaphragms are rated for –34 to 71°C (–30 to 160°F). Installation and Mounting Procedures
Verify the 25%, 50%, and 75% travel points against the corresponding input signals (e.g., 6, 9, and 12 psig for a 3–15 psig range). Maintenance and Troubleshooting Common maintenance tasks involve:
Used when the actuator has tapped holes in the posts.
During installation, it is vital to correctly set the based on the actuator travel. For travels between 20 and 30 mm, the long portion of the plate's slot should be closest to the positioner. Calibration Steps for the 3560
Set the input signal to its minimum (e.g., 3 psig) and adjust the nozzle until the output gauge shows the valve is at its starting position.
The unit requires clean, dry, non-corrosive air or natural gas.
Standard ranges include 0.2 to 1.0 bar (3 to 15 psig) or 0.4 to 2.0 bar (6 to 30 psig).
The provides two primary mounting methods:
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
Increase the input signal to the maximum (e.g., 15 psig). Adjust the flapper assembly or span adjustment screw until the valve reaches the full intended travel.
