Brand: Festo

Quarter turn actuator DFPD-120-RP-90-RS30-F0507-R3-EP

The Festo 8048143 single-acting gear rack/pinion industrial component features a valve actuator size of 120, an F0507 flange hole pattern, and a nominal swivel angle of 90 degrees with an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle. Operating at pressures between 2 bar and 8 bar (29 psi to 116 psi) with a nominal operating pressure of 3 bar (43.5 psi) and a burst pressure of 24 bar, it includes a VDI/VDE 3845 NAMUR valve connection, a VDI/VDE 3845 Size AA 1 positioner connection, a 19 mm shaft connection depth, and an ISO 5211 standard valve connection supporting any mounting position. Certified as a VDMA 66413 safety device, it executes its safety function via spring force to switch to the defined safety position upon air exhaustion, supporting up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in redundant architectures per 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.

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.
