Festo
8102894
Quarter turn actuator DFPD-900-RP-90-RS35-F14-R3-C-VDE2
The Festo 8102894 is a single-acting industrial valve actuator featuring a size 900 gear rack and pinion structural design, a 90-degree swivel angle, and an ISO 5211 standard valve connection. This safety device operates at a nominal pressure of 3.5 bar (0.35 MPa / 50.75 psi) with an operating pressure range of 2 bar to 8 bar (0.2 MPa to 0.8 MPa / 29 psi to 116 psi) and a burst pressure of 24 bar. It includes an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle, a 38 mm shaft connection depth, an F14 flange hole pattern, and VDI/VDE 3845 (NAMUR) valve connection compliance. Certified to ISO 13849 and IEC 61508, the safety function executes via spring force to switch the actuator to a defined safety position when compressed air is switched off and the spring chamber is exhausted, supporting up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
