Quarter turn actuator DFPD-N-120-RP-90-RS35-F07-R3-C

The Festo part number 8102821 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 120 and an F07 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, a 19 mm shaft connection depth, and an operating pressure range of 2 bar to 8 bar (29 psi to 116 psi) with a nominal operating pressure of 3.5 bar (50.75 psi) and a burst pressure of 24 bar. Certified as a safety device to ISO 13849 and IEC 61508 for use up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture, the safety function executes via spring force 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.

Engineering context

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.
