Brand: Festo

Quarter turn actuator DFPD-120-RP-120-RD-F0507

The Festo industrial component 8065341 is a double-acting gear rack and pinion valve actuator featuring a size 120 designation, a 120-degree swivel angle, and an F0507 flange hole pattern with a 19 mm shaft connection depth. Operating 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), this unit achieves a burst pressure of 24 bar and utilizes an ISO 5211 standard connection for valves along with VDI/VDE 3845 (NAMUR) compliance. Certified for safety functions to ISO 13849 and IEC 61508, the safety device supports low demand mode up to SIL 2, high demand mode up to SIL 1, and up to SIL 3 in a redundant architecture, functioning by switching to a defined safety position when pressurized.

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

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.
