Brand: Festo

Quarter turn actuator DFPD-900-RP-90-RS45-F14-R3-C

The Festo part number 8102889 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 900, an F14 flange hole pattern, and a nominal swivel angle of 90 degrees that includes end-position adjusting ranges of -5 degrees to 5 degrees at both 0 degrees and the nominal angle. Operating at pressures between 0.2 MPa and 0.8 MPa with a 24 bar burst pressure, this safety device incorporates a spring assembly to switch to a defined safety position upon exhaust of the compressed air, 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. It includes a 38 mm shaft connection depth, an ISO 5211 standard valve connection conforming to VDI/VDE 3845 (NAMUR), and a VDI/VDE 3845 Size AA 3 connection point for positioners and position sensors for mounting in any position.

Why 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.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
