Brand: Festo

Quarter turn actuator DFPD-120-RP-180-RD-F0507

The Festo 8065339 is a double-acting industrial valve actuator featuring a gear rack and pinion structural design with a 120 size, a 180-degree swivel angle, and an ISO 5211 standard valve connection. Certified for safety functions to ISO 13849 and IEC 61508, it operates at a nominal pressure of 5.5 bar (79.75 psi) with an operating range of 2 bar to 8 bar, and supports safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture. This safety device closes to the right, accommodates F0507 flange hole patterns with a 19 mm shaft connection depth, and features VDI/VDE 3845 compliance 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.

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

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.
