What to do if excessive fluid leaks downstream of the Azbil Control Unit valve?

  Mrs. Denise WadeAug 10, 2025
  If you observe excessive fluid leaking downstream of the Azbil Control Unit valve, even when the valve opening is unchanged, several factors could be at play. First, check for air leakage in the actuator by applying supply air or atmospheric pressure and inspecting the air source and positioner. Also, verify if the valve opening is truly at zero by checking the lift. Finally, inspect the plug or seat ring for corrosion or erosion, and check for any jamming on the guide. Replacement of parts may be required.

Why is the Azbil Control Unit valve operation unstable and hunting at the fully closed position?
- R
  robertreeseAug 15, 2025
  If the Azbil Control Unit valve operation is unstable, exhibiting hunting behavior when fully closed, consider these potential causes. The valve capacity might be too large, necessitating a reduction in Cv, and for a single valve, ensure the flow direction is correct. Check if another line is using an excessively large volume of air, considering pipe capacity, restrictions, and air supply source capacity. Also, inspect the controller output for hunting issues originating from the positioner itself, and repair or replace the positioner if necessary. Finally, if process fluid pressure impacts the valve, replace the actuator with a larger one.

Why is the Azbil Control Unit valve operation sluggish?

  Harold BennettAug 20, 2025
  If the Azbil Control Unit valve operation is sluggish, several factors could be responsible. First, check for air leakage from the actuator in the pneumatic pipe. Also, check for any foreign matter adhering to the plug’s guide. Hardening of the gland packing, leading to increased hysteresis, can also cause sluggishness. Lastly, a faulty positioner might be the culprit, so try it on another line's positioner.

What causes the Azbil Control Unit valve to vibrate?
- M
  Michele ManningAug 26, 2025
  If the Azbil Control Unit valve vibrates, there are several possible causes. Check if the pipe on which the valve is mounted is vibrating and enhance its support if needed. Search for other sources of vibration. If there is erosion of the plug and guide, replace the parts. If there is a change in process fluid condition, modify the orifice or Cv coefficient. Finally, consider changing the plug type to alter the characteristics.
