Festo
The Festo 8102909 is a single-acting industrial component utilizing a gear rack and pinion structural design with a valve actuator size of 2300 and an F16 flange hole pattern. Certified for safety functions to ISO 13849 and IEC 61508, the unit achieves safety ratings up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture, utilizing spring force to switch to a defined safety position upon compressed air exhaustion. It features a 90-degree swivel angle with an end-position adjusting range of -5 to 5 degrees at both 0 degrees and the nominal swivel angle, an ISO 5211 standard valve connection, and a VDI/VDE 3845 NAMUR valve connection conforming to size AA 3 for positioners and sensors. Operating at a nominal pressure of 4.5 bar (0.45 MPa) within a range of 2 bar to 8 bar (29 psi to 116 psi) and a 24 bar burst pressure, the component accommodates a 48 mm shaft connection depth and any mounting position while closing to the right.
