What to do if my Flowserve Valve Positioners position is driven fully open or closed?
- R
  Rhonda WilsonJul 27, 2025
  If the position is driven fully open or closed and not responding, perform a stroke calibration (Quick-Cal). Verify hardware connections of the inner-loop hall sensor. Check ATO (Air-to-open) and ATC (Air-to-Close) settings and recalibrate using Quick-Cal to apply settings. Also, verify ATO/ATC actuator tubing. Consider replacing the electro-pneumatic converter or adjusting the inner-loop to see if proper control resumes.

Why Flowserve Valve Positioners valve position reading is not what is expected?
- D
  Derek CurryAug 1, 2025
  If the valve position reading is not as expected, reposition the stem position sensor if it's mounted off by 180 degrees. Perform a stroke calibration (Quick-Cal). Verify tight shutoff settings and check if custom characterization or soft-stop limits are active.

Why is my Flowserve Valve Positioners unit not responding to analog commands?
- V
  Vincent RiosAug 6, 2025
  If the unit isn't responding to analog commands, it might be in digital command mode. Switch to analog command mode using the procedure outlined in Section 22.3 Command Source Reset, use the ValveSight® DTM, or use a handheld communicator. Also, check for any errors that occurred during calibration and correct them.

How to fix sticking or hunting operation of the Flowserve Valve Positioners?
- C
  Chad WoodsAug 11, 2025
  To address sticking or hunting, check the air supply for proper filtering and adherence to ISA specifications ISA-7.0.01 due to possible contamination of the electro-pneumatic converter. Lower proportional gain settings if control tuning parameters are incorrect. Enable the stability DIP switch on the local interface and recalibrate if packing friction is high; if the problem persists, adjust the pressure control window with a handheld communicator or ValveSight® and recalibrate. Additionally, disassemble and clean the spool valve if it is corroded or dirty.

Why Flowserve Valve Positioners has erratic communications?
- C
  Christopher SmithAug 17, 2025
  Erratic communications can be due to several factors. Ensure the current source bandwidth is limited to 25Hz, with a maximum allowable current source rate of change of 924 mA per second. Check the cable size, length, and capacitance. Verify that the laptop battery is not low if using a HART modem connected to a PC RS-232 port. Confirm you're using a HART-compatible I.S. barrier. If the current source is stripping the HART signal, use a 250? resistor and a 22 µF capacitor to create a HART filter according to the schematic: 22 µF 250? ?

What to do if no LED is blinking on Flowserve Valve Positioners?
- D
  dennis61Aug 21, 2025
  If no LED is blinking, verify the current source supplies at least 3,8 mA. Also, verify the voltage source supplies at least 10VDC. Check the wiring for correct polarity.
