EHAZ^®

Individual, compact, multipurpose

Fahlke offers the most individual electro hydraulic actuator units currently available. The modular technology (MCE) in the control ensures the highest level of compactness, user friendliness and operability. With the totally individually configurable electro hydraulic control units nothing stands in the way of perfect process adaptation and therefore ideal valve automation, right up to central hydraulic controls for multiple actuator controls, SSX, SAV or any other type of automatic safety shutoff valves. You have a choice among numerous components which can be integrated in the control such as solenoid valves, hand pumps, pressure limit valves, line break detector systems for all your valves, standard or control safety processes or for high and low pressure security, differential pressure controls can also be integrated for your valve automation. Fahlke controls and actuators are leaders with regard to current consumption and handling. With individualized process adjustment and many advantages this represents the key to the safe automation of your equipment.

The advantages

• Remains fully operational even after several weeks without power (bladder accumulator, spring technology, hand pump)
• Torque can be increased or decreased by adjusting the operating pressure
• No chance of leaks since the MCE technology contains no pipes or screw-on fittings such as those found in conventional controls
• Very compact drive unit
• Corrosion-free thanks to stainless steel and a hard-coated aluminum alloy
• MCE technology allows easy maintenance
• Highly effective despite low power consumption
• Very short (1 - 2 sec.) or very long actuation times possible
• Opening and closing times can be adjusted as required
• No necessity of additional supply lines – no need for air or air lines to the pipeline
• Gas or operating media cannot escape into the atmosphere (sealed system)
• Greatest degree of environmental friendliness of all actuator systems
