… compact, powerful, and reliable electro-hydraulics - the solution for your future challenges

The electro-hydraulic valve actuator from HOERBIGER stands out with its high energy density. High forces and torque levels can be implemented despite a small overall size. HOERBIGER combines with this compact unit the high power density and precision of the hydraulic system with the benefits of an electric actuator:

- High power density in compact overall size
- Safety due to Fail-Safe and Emergency Shutdown
- Pressure-encapsulated application in hazardous areas

Optimal system modules for the automation of industrial valves
The electro-hydraulic drive module from HOERBIGER combines the motor, pump, and tank into a compact functional unit. 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.

technical data:
Torque for rotational drive up to 50 kNm
Actuating force for linear drive up to 200 kN
Minimum actuating time 1 sec
Ambient temperatures -25 to +70°C
Protection class IP 65

Options:
ESD with energy storage,
Emergency manual actuation,
Rapid actuation,
Torque-dependent speed control,
Protection class IP 68,
SIL 3-compliant for safety-relevant functions,
ATEX – II 2G EEx d IIB T4 due to pressure-tight encapsulation.

Operation 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.

Performance
The automatic speed adjustment guarantees gentle operation in the final positions when opening and closing a valve. Operationally relevant 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.
