Brand: Festo

Quarter turn actuator DFPD-N-240-RP-90-RD-F0710

The Festo industrial component, part number 8066414, is a double-acting gear rack and pinion valve actuator featuring a size of 240, an F0710 flange hole pattern, and a nominal swivel angle of 90 degrees with an end-position adjusting range of -5 to 5 degrees at both 0 degrees and the nominal angle. It operates within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal operating pressure of 5.5 bar (79.75 psi) and a burst pressure of 24 bar, while conforming to ISO 5211 and VDI/VDE 3845 NAMUR standards. Certified for safety functions to ISO 13849 and IEC 61508, the device functions as a safety device providing safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture.

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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Devices type according to VDMA 66413: Safety device
Safety function: The safety function consists of the actuator switching to the dened | safety switching position. This switching movement is achieved by | pressurizing the corresponding pressure chamber with compressed air. | The value of the torque generated depends on the pressure diﬀerence | between the two pressure chambers separated by the piston.
Safety integrity level (SIL): Up to SIL 2 low demand mode | up to SIL 3 in a redundant architecture | up to SIL 1 high demand mode
Certied for safety function to ISO 13849 and IEC 61508 (SIL): Product can be used in safety-related parts of control systems up to SIL | 2, low demand | Product can be used in safety-related parts of control systems up to SIL | 1, high demand | up to SIL 3 in a redundant architecture

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.
