Brand: Festo

Quarter turn actuator DFPD-N-20-RP-90-RS60-F05-R3-C

The Festo part number 8102801 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 20 and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar and a nominal operating pressure of 6 bar, this safety device incorporates an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle. The unit includes an ISO 5211 standard connection for valves, a VDI/VDE 3845 NAMUR valve connection, an F05 flange hole pattern, a 12 mm shaft connection depth, and VDI/VDE 3845 Size AA 1 connection points for positioners and position sensors. Certified for safety functions to ISO 13849 and IEC 61508, the unit provides low demand mode up to SIL 2, high demand mode up to SIL 1, and up to SIL 3 in a redundant architecture, where 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.

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.
