PAZ®

(10 Nm – 5.000.000 Nm)

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

PERFECT AUTOMATION OF VALVES FROM 1″ TO 60″

Fahlke PAZ® pneumatic actuators offer the quality and reliability of products made in Germany. Automation requirements are optimally fulfilled by the extensive line of Fahlke PAZ® actuators, with more than 250 actuating cylinder variants. All Fahlke pneumatic actuators are maintenance-free and waterproof in accordance with IP68.

Our actuator cylinders are of the highest quality. They are fully welded, honed, nickel-plated and therefore absolutely maintenance-free. Cylinder leaks such as those in other designs resulting from expanding tie-bars, bolts, etc. cannot occur. The PAZ® actuator features a special adapter system that ensures fast and easy mounting on any valve. The PAZ® is also available as a regulating actuator (PAZ-R®) and with a safety shutdown valve (SSV) and can of course be equipped with a pressure reserve tank and hand pump unit, as well as spring opening or closing for emergency actuation.
