Cross-reference check

Relationships and limits.

  • AC69536 repeats at three separate items in the same hydraulic equipment figure.
  • All three rows carry SB29-3225 and CMM 29-09-65, with no printed alternate or replacement.
Important limit

Three catalog placements do not mean the valves can be moved between positions without a configuration check. The IPC does not print a superseding number or test setting.
