Demonstrates basic principles of hydraulics and control systems.
User can see operations inside of hydraulics valves and valve structures.
User can put an air bubble in the FESTECH transparent hydraulics power unit to understand the
operating principles of hydraulics in valves.
Plumbing system is conveniently connected by quick coupling connector.
