How to fix a CLA-VAL 131-01 that fails to close?
- K
  Kelly CarrAug 10, 2025
  To address a CLA-VAL Control Unit that fails to close, start by opening any closed isolation valves in the control system or main line. Then, inspect the upstream pressure, pilot system, strainer, tubing, valves, or needle valves for any obstructions that might be causing a lack of cover chamber pressure. If the issue persists, the diaphragm may be damaged and require replacement. Also, clean and polish the valve stem if there's corrosion or excessive scale buildup, and inspect for any damaged parts. Remove any mechanical obstructions lodged in the valve. Finally, check for a worn disc or badly scored seat, and replace them if necessary.

  If your CLA-VAL Control Unit fails to open, begin by opening any closed isolation valves located upstream or downstream in the main line. Next, verify that there's sufficient line pressure, ensuring a minimum of 5 psi flowing line pressure differential. If the problem continues, inspect the diaphragm assembly for corrosion or excessive buildup on the valve stem, cleaning and polishing the stem as needed, and replace any damaged parts. For valves in reverse flow, consider the possibility of a damaged diaphragm, and replace it if necessary.
