DEHAZ^®

electro hydraulic actuator unit for operation with alternating current

The DEHAZ is characterized by minimum expenses for operating, installation and maintenance. Ideal where 230 VAC, 380 VAC or 400 VAC power is available. This actuator technology can be quickly mounted on any valve. No gas or air lines are required to operate the actuator.

Powerful, distance stable, reliable

As is the case with every Fahlke actuator, the DEHAZ represents a perfect, economical automation solution and can be found, for example, in gas pipeline compressor stations or – in its non-explosion proof version - for automating water lines.

The DEHAZ is capable for automating all types of ball valves, butterfly valves, plug valves, louvers, dampers and other 90° valves.

The advantages

• Variable and adjustable torque
• The power consumption of the Fahlke DEHAZ actuator is a mere 1/10 that of purely electric actuators operating at the same torque and with the same actuation time.
• The actuation time can be adjusted in both directions in order to achieve an optimum adjustment of the control process.
• Easy installation on every valve.
• Power supply possible over longer distances.
• The DEHAZ can be mounted up to 1,000 m from the power supply.
• Based on the narrower cable diameter, the cable connection is simpler and significantly more economical than is the case with a comparable electric actuator.
• Available with emergency hand pump actuation system.
