Festo
The Festo part number 8102903 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 1200, an F14 flange hole pattern, and a nominal swivel angle of 90 degrees that closes to the right. Operating within a pressure range of 2 bar to 8 bar and a nominal operating pressure of 3.5 bar, this safety device includes an end-position adjusting range of -5 deg to 5 deg at both 0 degrees and the nominal swivel angle, a 38 mm shaft connection depth, and an ISO 5211 standard valve connection that conforms to VDI/VDE 3845 (NAMUR). The integrated safety function relies on spring force to switch the actuator to a defined safety position when compressed air is switched off and the spring chamber is exhausted, supporting safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture according to ISO 13849 and IEC 61508 certifications.
