GHAZ®II

Gas over oil actuators

 

Fahlke GHAZ®II

gas over oil actuators are used worldwide in numerous variants by all leading gas providers for standard open-close applications as well as safety-related applications. They are always used when a safe automation is required.

 

GHAZ®II actuators work without pressure reduction due to their completely welded, high-quality workmanship of the operating cylinders. This allows the direct pipeline pressure to be used. This results in compact and easily mountable automation units.

 

GHAZ®II actuators are supplied with high or low-pressure controls. These can be equipped with solenoid valves for easy open-close operation to pressure pilots or line break detection systems for pipeline protection.
