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.
