Serie PT

High-quality stainless steel alloys for
demanding environments

PT series

The rotary actuator series PT is completely made of stainless steel and is, thanks to the use of high-quality stainless steel alloys, ideally adapted for use in the most aggressive environmental conditions or for applications with strict hygiene restrictions. The proven rack and pinion design ensures a long service life and reliable application in continuous operation even under the toughest conditions.

Due to the design with internal slide bearings, the PT series actuators are absolutely maintenance-free. The requirements for easy maintenance are also fully met thanks to the actuator principle and the captivated safety springs.

Thanks to the consideration of all common market standards for the connection interfaces, the PT actuator series offers maximum modularity when combined with valves and accessory components such as solenoid valves, limit switches or positioners.
