SEHAZ® ECO

(20 Nm – 60.000 Nm)

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

SEHAZ® ECO ELECTRO-HYDRAULIC ACTUATOR

A NEW DIMENSION IN SAFETY

The new SEHAZ® Eco is the most modern automation unit currently available. This version is the successor to the time-proven SEHAZ®, which has been in use worldwide since 1994 by all major oil and gas suppliers for automation of their pipeline networks.

The automation unit is designed for maximum operational safety and combines a compact design with minimal mounting weight.

PRODUCT INFORMATION

Our explosion-proof SEHAZ® Eco actuator is designed for maximum safety with up to four integrated safety systems that guarantee 100% availability even in the event of a power outage.

The Fahlke SEHAZ® Eco automates all 90° rotary and linear valves. Use of the SEHAZ® Eco reduces costs for energy, operation, installation and maintenance of your automation application to a fraction of the costs of conventional products. The unbeatable low energy consumption of our SEHAZ® Eco actuators will improve your CO2 balance.
