Festo
557620
Semi-rotary actuator DFPB-180-090-S6-F1012
The Festo 557620 is a single-acting industrial component featuring a rack and pinion design structure with a size 180 actuator, F1012 flange hole pattern, and a 90-degree swivel angle. Operating at a nominal working pressure of 5.6 bar and maximum working pressures up to or equal to 8 bar, this unit functions with compressed air conforming to ISO 8573-1:2010 [7:4:4] and includes NAMUR-standard valve connections based on VDI/VDE 3845 without cushioning or position detection. Rated for ATEX gas category II 2G (c T4 X) and dust category II 2D (c 125°C X) in ambient temperatures from -20°C to 80°C, it achieves Safety Integrity Level (SIL) up to SIL 3 in Low Demand mode and allows for lubricated operation.
