PLAZ®

As reliable as versatile

 

Fahlke PLAZ® pneumatic linear actuators offer quality and reliability made in Germany. Automation requirements are perfectly met, thanks to the large line of Fahlke PLAZ® actuators with its many operating cylinder variants. All Fahlke pneumatic actuators are maintenance-free and waterproof in accordance with IP68. The interior surface of all cylinders is honed, made of chemical nickel and is corrosion-free and completely welded. The PLAZ® actuator offers a special adaptor system, which ensures a rapid assembly on any valve. The PLAZ® is also available as a regulating actuator (PLAZ-R®) and a safety shutdown valve (SSV) and can of course be supplied with a pressure reserve tank and hand pump unit for emergency actuation.

 

All linear valves in the sizes 1″ to 60″ as well as a force range of 10 to 1,000,000 N can be automated.
