HY132– Hydraulics (3) Proportional

HY132– Hydraulics (3) Proportional

You will become familiar with the function and actuation of proportional (dynamic) valves and the design of basic circuits in relevant industrial applications. The extensive practical part provides you with an opportunity to design circuits, adjust parameters and gain experience of commissioning and troubleshooting in proportional hydraulic control systems.

Target group

The course is aimed at anyone who is faced with proportional hydraulics in their practical work. The high level of practical relevance makes the course particularly suitable as a supplementary course for instructors.


  • Basic principles of proportional hydraulics
  • Design, function and characteristics data for proportional, directional control, pressure and flow control valves
  • Generation of target values (analog and digital)
  • Adaptation of amplifier electronics to required conditions
  • Development and interpretation of proportional hydraulic circuit diagrams
  • Intensive practical training involving design based on circuit diagram and adjusting parameters for optimum commissioning
  • Instructions for maintenance, troubleshooting and commissioning
  • Introduction to servo valve technology and control
  • Proportional valves in open control loop systems, control valves in closed control loops
  • Current standards and safety regulations for practical operation and exercises

The Participant:

  • understands the principles of proportional hydraulics
  • can explain the structure and mode of operation of proportional way, pressure and flow control valves
  • can interpret the characteristics data of proportional valves
  • can adapt amplifier electronics to the required conditions
  • can develop and read proportional hydraulic circuit diagrams
