THE COMPACT EXPLOSION-PROOF ELECTRO-HYDRAULIC ACTUATOR

The extremely compact and powerful GEHAZ® Eco from Fahlke is part of the world’s most modern actuator series for automation of rotary valves. Our economical electro-hydraulic automation technology can be mounted on every valve, has a variable torque and is explosion-proof in accordance with Ex II 2G Ex db eb IIC T6 Gb.

It is ideal for smaller valves (e.g. gate and ball valves), since the compact size enables fast and easy mounting on such valves.

Our electro-hydraulic actuator unit also scores with respect to cost effectiveness: The GEHAZ® Eco uses only 1/10 the power of an electric actuator with the same torque output. In addition, our actuators convince with absolute reliability and low installation and operating costs.
