Brand: Festo

Quarter turn actuator DFPD-N-480-RP-90-RD-F1012-R3-EP

The Festo 8066421 is a double-acting industrial valve actuator featuring a size of 480, a gear rack and pinion structural design, and an ISO 5211 standard valve connection with an F1012 flange hole pattern. Operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) and a burst pressure of 24 bar, this safety device achieves a 90-degree swivel angle with adjustable end-positions from -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle. Certified to ISO 13849 and IEC 61508, the component supports safety functions 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.

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
Burst pressure: 24 bar
Operating pressure: 0.2 MPa...0.8 MPa | 2 bar...8 bar | 29 psi...116 psi
Nominal operating pressure: 0.55 MPa | 5.5 bar | 79.75 psi

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.
