Electronic Control Systems

Ruppel Hydraulics develops specialised proportional control amplifiers for hydraulic and pneumatic applications that enable precise and efficient control of proportional valves. These amplifiers are critical for the accurate control of flow and pressure in various systems and are used in a variety of industrial and mobile applications.

Technical Data

Our bladder accumulators are characterised by their versatility and high-quality workmanship:

Converts electrical input signals (voltage or current) into proportional control currents for hydraulic and pneumatic valves.
Adjustable parameters

  •  Minimum and maximum currents (I min, I max):
  • Adjustable for optimum
    control of the valve
  • Dither frequency: Adjustable to minimise friction and hysteresis in the valve minimise

  •  Short-circuit protection: Prevents damage due to electrical overloads
  • Overcurrent protection: Secures the system in the event of excessive
    current loads
  • Freewheeling diode: Protects against reverse currents in the magnetic circuit

  •  External release or interlock for safe control and deactivation of the system
    deactivation of the system
  • Customisable software for specific requirements

Applications

Our proportional control amplifiers are used in various areas:

Converts electrical input signals (voltage or current) into proportional control currents for hydraulic and pneumatic valves.

Efficient control of hydraulic systems in construction machinery, commercial vehicles and agricultural equipment.

Used in robotics and automation for precise motion control.
