Festo
The Festo 8102803 is a single-acting industrial valve actuator featuring a gear rack and pinion structural design, a size 40 actuator, and an F05 flange hole pattern. It provides a 90-degree swivel angle with an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle, operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) and a burst pressure of 24 bar. Configured for a right-closing direction, this safety device includes a spring-driven safety function that switches the actuator to a defined safety position when compressed air is removed and the spring chamber is exhausted, achieving certifications up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture per ISO 13849 and IEC 61508.
