A crucial read. It explains the force balance system:

"We’re down!" Kael yelled, scrambling up the metal steps, clutching a tablet computer. "The DCS is screaming. The flow transmitter says zero, but the upstream pressure is spiking. The valve is stuck closed. I need you to bypass it." Correct installation is critical for performance

Zero and span controls interact. Repeat steps 1 through 4 until no further adjustment is required. Troubleshooting Common Issues Potential Cause Corrective Action Valve hunts or oscillates

Usually up to 100 psi, but must be regulated to the actuator's limit. Input Signal: Standard pneumatic ranges (3–15, 6–30, or 5–25 psi). Operating Temperature: Limits | Standard: -40°C to 82°C (-40°F to

As the valve stem moves, the feedback linkage (or cam in rotary models) applies a counter-balancing force to the beam via a feedback spring.
