Pressure Control in the Electrohydraulic Power Unit (.PDF Download)

Control using electrohydraulic proportional or servo valves is usually achieved by using a power unit that maintains a constant inlet pressure to the control valve. Such a design strategy offers several advantages and raises several issues:

  • With a high-pressure supply, hydraulic power is available immediately when a signal is given to open the valve. That is, there is no need to wait for pump pressure to build before flow occurs and the load moves.
  • Conventional servo
