Name: Festo 8042197 Quarter turn actuator DFPD-3500-...
Brand: Festo

Quarter turn actuator DFPD-3500-...

The Festo industrial component, part number 8042197, features a valve actuator size of 3500 with an F16 flange hole pattern, a 90-degree swivel angle, and an end-position adjusting range of -5 to 5 degrees at both 0 degrees and the nominal swivel angle. Operating via double-acting or single-acting modes utilizing a kinematic yoke system and gear rack/pinion structural design, this unit supports a standard valve connection conforming to ISO 5211 and VDI/VDE 3845 (NAMUR), an operating pressure of 2 bar to 8 bar, and a burst pressure of 24 bar. It includes certified safety functions compliant with ISO 13849 and IEC 61508 for SIL 2 low demand mode and SIL 3 in a redundant architecture, functioning in any mounting position with a shaft connection depth of 48 mm to 50 mm.

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. | 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

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.
