(20 N – 7.000.000 N)

Since 1975 Fahlke has offered a comprehensive selection of actuators for your automation projects.


The Fahlke EHLAZ® Eco is the most individual electro-hydraulic actuator unit currently available. The modular technology (MCE) in the control unit ensures maximum compactness, user friendliness and operational capability. The individually configurable EHLAZ® Eco ensures perfect process adaptation and therefore the ideal automation solution.

You have the choice between numerous components for integration in the control unit, such as solenoid valves, hand pumps, pressure pilots and line break detection systems. For all standard or regulating processes of your valves or for high- and low-pressure protection, differential pressure controls can be integrated in your automation process. Fahlke EHLAZ® Eco control units and actuators are the leaders with respect to power consumption and handling. Together with custom process adaptation this is the key for the safe automation of your systems in a force range up to 1,000,000 N.
