Name: Festo 8042195 Quarter turn actuator DFPD-1200-
Brand: Festo

Quarter turn actuator DFPD-1200-

The Festo 8042195 is a gear rack/pinion industrial component featuring a valve actuator size of 1200, an ISO 5211 standard valve connection, and an F14 or F1012 flange hole pattern. It operates in double-acting or single-acting modes with a 90-degree swivel angle, an operating pressure of 0.2 MPa to 0.8 MPa, a burst pressure of 24 bar, and an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle. Certified for safety functions to ISO 13849 and IEC 61508, this safety device delivers SIL 2 low demand mode, SIL 1 high demand mode, and up to SIL 3 in a redundant architecture, incorporating VDI/VDE 3845 (NAMUR) valve connections and size AA 3 positioner connection points.

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.

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. | The safety function consists of the actuator switching to the dened | safety switching position when the compressed air is switched oﬀ and | the spring chamber is exhausted. This switching movement is achieved | through the spring force of the spring assembly.
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.
