Cascade circuit with Multiple Cylinders

Cascade circuits are used in many places, some of the most common include refrigeration and industrial production lines.

Cascading is used to turn on and off sensors to prevent:


  • Out of sequence operation
  • Inadvertent operation
  • Prevent locked signals

Cascade circuits also:


  • Provide a standard method of solving any sequence (no locked on pilot signals)
  • Uses one memory valve (group changing valve) for each sequential step
  • Shift register circuits are similar to cascade
  • Use one logic valve for each step
  • PLC’s provide a solution for medium to complex systems

APT cover these types of circuits in their 6-day Fluid Power course.
