# How to calibrate an ABB regulation valve (FCV)
## This guide describes how to perform a calibration of an ABB regulation valve using the local actuator interface. (FCV)
#### When to use this guide
Use this procedure when:
- A regulation valve has been installed or replaced
- Valve position feedback does not match the actual valve position
- The actuator has lost its calibration
- Commissioning or troubleshooting requires recalibration
- Internal leaking is observed - Flow readings on corosponding Flow transmitter even when FCV is at 0% or no flow readings when it is at 100%.
---
#### Preconditions
Before starting the calibration:
- The system is in a **stoptate**
- The valve can move freely between end positions
- Power and air is supplied to the valve actuator
- No active interlocks prevent valve movement - Valve is in auto on HMI.
---
#### Step-by-step calibration procedure
1. **Remove the front cover** of the ABB valve actuator.
2. **Press and hold the “F” push button for 5 seconds**.
3. The menu **“ADJ\_ROT”** will appear on the display.
**Press and hold the “F” push button again for 3 seconds**.
- The calibration sequence will start automatically.
1. **Wait until the calibration sequence is finished**.
- This may take **a few minutes**.
2. Once calibration is complete, **adjust the visual position indicator if needed**:
- Remove the indicator
- Re-mount it so it correctly reflects the actual valve position
After calibration move the valve from 0% to 30% to 60% to 100% from the skids HMI and check if local display and HMI reading matches within +/- 1%.
---
#### Notes and common mistakes
- Do **not interrupt power** during the calibration sequence
- Ensure the valve is not mechanically blocked
- Calibration may fail if the valve cannot reach its full stroke
---
#### When to stop and contact LiqTech Service
Stop the procedure and contact LiqTech Service if:
- The calibration does not complete, even after an hour.
- Error messages appear on the actuator display
- The valve position remains incorrect after recalibration
