The anti-surge valve we are using on site has a FISHER DVC6030 actuator, and it is a butterfly valve. During the valve calibration process, when a signal was sent to the valve, there were slight fluctuations at several opening degrees below 10%. The airtightness of the valve’s air supply system was checked and found to be fine; this issue did not occur during previous calibrations. It appeared this time, and the valve moved 2-3 times, with the point of fluctuation varying each time. I would like to ask the experts: what could be the cause of this? How should this be solved?

The control performance of butterfly valves is the same as well, especially at low opening angles

We have encountered a similar situation as well. Have you guys at Haiyou figured out the cause?
