Brand: Festo

Quarter turn actuator DFPD-N-120-RP-90-RS30-F0507

The Festo part number 8066446 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 120 and an F0507 flange hole pattern. Operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal 3 bar (43.5 psi), this safety device provides a 90-degree swivel angle with adjustable end-positions from -5 degrees to 5 degrees at both 0 degrees and the nominal angle. Certified for safety functions to ISO 13849 and IEC 61508, the unit achieves up to SIL 2 in low demand mode and SIL 3 in a redundant architecture, utilizing spring force to switch to the defined safety position when compressed air 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.
