Name: Festo 557614 Semi-rotary actuator DFPB-670-090-F1012
Brand: Festo

Semi-rotary actuator DFPB-670-090-F1012

The Festo 557614 is a double-acting rack and pinion industrial component featuring an actuator size of 670, an F1012 flange hole pattern, a 90-degree swivel angle, and a VDI/VDE 3845 NAMUR-compliant valve connection. Operating within a working pressure range of 1 to 8 bar at a nominal 5.6 bar using ISO 8573-1:2010 [7:4:4] compressed air, this unit functions across an ambient temperature range of -20°C to 80°C and holds ATEX certifications for II 2G c T4 X gas and II 2D c 125°C X dust protection up to SIL 3 Low Demand mode. It incorporates no cushioning or position detection, allows for lubricated operation, and permits assembly in any position within an explosion-proof ambient temperature range of -20°C to +80°C.
