(20 Nm – 1.200.000 Nm)

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

GAZ® GAS ACTUATOR – designed for high pressure

Fahlke offers high-quality products made in Germany for safe automation of your gas pipeline and delivers hundreds of gas actuator versions and control units every year for standard open/close applications, regulation or custom designs from 1″ – 60″ valves, 20 Nm – 1,200,000 Nm. GAZ® actuators can be equipped with safety multi-spring technology, emergency hand pumps or integrated line break detection systems.

Fahlke GAZ® actuators are delivered with high- or low-pressure control units, switched by pressure pilots for pipeline protection, or simply with solenoid valves for open/close operation. The fully welded cylinder technology and control quality of GAZ® actuators allows operation with the direct pipeline pressure, without the need for pressure reduction.

All Fahlke double action GAZ® actuators or spring return actuators are maintenance-free and waterproof in accordance with IP68. This technology and the special Fahlke adapter system allow installation on any 90° valve within less than one minute.
