Standard nitrile O-rings and diaphragms are rated for –34 to 71°C (–30 to 160°F). Installation and Mounting Procedures
Understanding the performance limits of the 3560 series is critical for safe operation:
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: Fisher 3560 Valve Positioner Manual Pdf
The provides two primary mounting methods:
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. Standard nitrile O-rings and diaphragms are rated for
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.
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
Involves attaching the positioner using studs and hex nuts to the back of the housing.
