Name: Festo 8042198 Quarter turn actuator DFPD-4500-...
Brand: Festo

Quarter turn actuator DFPD-4500-...

The Festo 8042198 industrial component is a double-acting and single-acting valve actuator featuring a size of 4500, a kinematic yoke system and gear rack/pinion structural design, and an ISO 5211 standard connection for valves with F16 and F1625 flange hole patterns. This unit provides a 90-degree swivel angle with an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle, a 50 mm to 57 mm shaft connection depth, and VDI/VDE 3845 NAMUR valve connections with a VDI/VDE 3845 Size AA 3 connection point for positioners and position sensors. Operating at a nominal operating pressure of 0.3 MPa to 0.6 MPa and an operating pressure range of 2 bar to 7.8 bar (29 psi to 113.1 psi) with a 23.37 bar burst pressure, the actuator supports any mounting position, features a safety function utilizing compressed air or spring force, and achieves SIL 2 low demand mode or SIL 3 in a redundant architecture certified to ISO 13849 and IEC 61508.

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

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.
