Name: Festo 8066460 Quarter turn actuator DFPD-N-240-RP-90-RS30-F0710-R3-EP
Brand: Festo

Quarter turn actuator DFPD-N-240-RP-90-RS30-F0710-R3-EP

The Festo part number 8066460 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 240 and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal operating pressure of 3 bar, this safety device includes a spring assembly that switches the actuator to a defined safety position when compressed air is switched off and the spring chamber is exhausted. Certified for safety functions to ISO 13849 and IEC 61508, the unit supports up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture, while conforming to ISO 5211 for standard valve connections and VDI/VDE 3845 for NAMUR valve connections and positioner mounting.

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.
