EHAZ® ECO
(20 Nm – 1.000.000 Nm)
Since 1975 Fahlke has offered a comprehensive selection of actuators for your automation projects.
EHAZ® ECO – AS INDIVIDUAL AS YOUR REQUIREMENTS
The Fahlke EHAZ® 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 EHAZ® 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 EHAZ® 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.
EHAZ® In DETAIL
YOUR ADVANTAGES AT A GLANCE
- Remains operational (bubble accumulator, spring technology, hand pump) even after a power outage
- Torque can be increased / decreased by adjusting the operating pressure
- No possibility of leakage, since MCE technology contains no pipes or fittings, as opposed to conventional control units
- Very compact actuator unit
- Non-corrosive due to use of stainless steel and a hard coated aluminum alloy
- Low costs
- Easy maintenance due to MCE technology
- High efficiency combined with low power consumption
- Very short (1 – 2 sec.) or also long actuating times are possible
- Opening and closing times can be adjusted as needed
- No additional supply pipes required (no air and gas connections to the pipeline)
- No escape of gas or fuels into the atmosphere (closed system)
- Maximum environmental compatibility and efficiency among all actuator systems
