(20 N – 1.000.000 N)

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


Fahlke PLAZ® pneumatic linear actuators offer the quality and reliability of products made in Germany. Automation requirements are optimally fulfilled by the extensive line of Fahlke PLAZ® actuators, with numerous actuating cylinder variants. All Fahlke pneumatic actuators are maintenance-free and waterproof in accordance with IP68. They are fully welded, honed, nickel-plated and therefore absolutely maintenance-free. The PLAZ® actuator features a special adapter system that ensures very fast mounting on any valve. The PLAZ® is also available as a regulating actuator (PLAZ-R®) and with a safety shutdown valve (SSV) and of course can be equipped with a pressure reserve tank and hand pump unit for emergency actuation.

All linear valves in sizes 1″ to 60″ and with a force range from 10 N to 1.000.000 N can be automated.
