Electrohydraulic actuators

Fahlke is the only manufacturer to have designed compact power units with a unique emphasis on safety, flexibility and environmental impact.

The major difference is the ability to change the torque.

By selecting electrohydraulic actuator for application, the customer can choose the most tailored drive from the SEHAZ, EHAZ, GEHAZ and DEHAZ product lines. These modern actuators are used for automation around the world. The possibility to set the torque of the selected value ensures reliable operation of the valves. This is an advantage electrohydraulic units over gas, pneumatic and gas-oil drives.

Valve torques change with their daily use and over time can significantly affect wear. Increasing valve torque can also occur through damage caused by media that is in contact with or due to long downtime. In extreme cases, a preset torque reserve is not sufficient.

The Fahlke Control System offers a solution to this problem by offering a series of SEHAZ, EHAZ, GEHAZ and DEHAZ electrohydraulic drives.

An additional advantage of electrohydraulic drives is their equipment in case of emergency:

– Fahlke actuators have an internal independent electrohydraulic system.

– The actuator can be fitted even with a quadruple safety system

– Even during a long period of power failure due to accumulated energy, control of valves is possible automatically – regardless of valve size, several opening and closing cycles are possible.

Fahlke electrohydraulic actuators are compact in design, exceptionally lightweight with unrivaled quality not available to other manufacturers.
