HOERBIGER ::

The electrohydraulic compact drive from HOERBIGER combines the advantages of hydraulics with the appearance of an electric drive system. The power supply and the signals required for actuation are controlled by an electrical interface. Once the drive system has reached its target position, the electric motor is shut off. This position is then maintained without any further energy requirement. The pressure-proof encapsulation enables the operation in extreme ambient conditions, to include in hazardous areas subject to explosions. Application-relevant additional functions for special performance features can be implemented through additional modules. Manual actuation, the reliable activation of safety functions, and the control of the actuating speed are possible at all times with this basic technology.

•  Operational safety
  The compact drive produces the necessary hydraulic actuating energy directly on the spot. Because of the unique design, failures due to defective tubing are excluded. The overload-protected torque transmission without mechanical gearbox enables a robust operation and protects the valve. Available for standard- and ATEX environments.
  
  
• Performance
  The automatic speed adjustment guarantees gentle operation in the final positions when opening and closing the valve. Operationally relevant safety functions, such as Fail-Safe and Emergency Shutdown, are a given for the electro-hydraulic drive.
  
  
• Efficiency
  The torque-dependent speed control and optional energy storage ensure low operating costs.
