Festo
The Festo 8066451 is a single-acting industrial component featuring a gear rack and pinion structural design with a size 240 valve actuator and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar and a burst pressure of 24 bar, this safety device utilizes spring force to switch to a defined safety position when compressed air is switched off and the spring chamber is exhausted. It includes an F0710 flange hole pattern, ISO 5211 standard valve connection, VDI/VDE 3845 NAMUR compliance, and VDI/VDE 3845 Size AA 2 connection points for positioners and sensors, while achieving up to SIL 2 in low demand mode and SIL 3 in a redundant architecture according to ISO 13849 and IEC 61508.
