Valve-disc selection

Match the Autotrol valve body and disc-kit reference

Pentair Autotrol valves route water with cam-operated flapper discs. Disc sets are documented by valve family and configuration; identify the 255 or Performa 263/268 body before selecting a kit. The controller mounted above the valve does not establish disc fitment.

Use the Autotrol identification guide. Water flowing after regeneration can involve debris, a disc that does not close, or a cam-position problem, so diagnose the valve before replacing the set.
