Compact power for potentially explosive environments
- Compact, electrically controlled actuator with ATEX certification
- Integrated safety functions
- High reliability and easy installation
Compact power – even for potentially explosive environments. That’s the strong point of the innovative electrohydraulic valve actuator made by HOERBIGER. It combines electric drive technology with the power density and high control dynamics of hydraulics.
The innovative valve actuator is operated entirely electrically via an interface, works independently, and requires no external hydraulic lines. The system is based on a proven compact power unit, which combines the tank, the pump, and the motor to form a powerful functional unit.
The innovative actuation concept from HOERBIGER offers benefits especially suited for the energy and process industries. In addition to the compact size compared to an electromechanical actuator, its explosion protection due to the pressure-proof encapsulation is a key performance characteristic for applications in this environment. Additional benefits are provided by optional safety functions such as quick action and emergency shut-down, manual operation, or the adjustment of the control speeds.
Reducing the HOERBIGER valve actuator to the electrical interface results in a compact design that allows easy and cost-saving installation. The actuator is largely maintenance-free–an overhaul is only required every three to five years.
