Brand: Festo

Quarter turn actuator DFPD-120-RP-90-RS60-F0507-R3-EP

The Festo 8048144 is a single-acting industrial component featuring a gear rack and pinion structural design with a size 120 valve actuator, an F0507 flange hole pattern, and a 90-degree swivel angle. Operating at a nominal pressure of 6 bar (0.6 MPa) with an operating range of 2 bar to 8 bar, this safety device includes an end-position adjusting range of -5 to 5 degrees at both 0 degrees and the nominal swivel angle, and conforms to ISO 5211 and VDI/VDE 3845 standards. It incorporates a safety function driven by spring force to switch to a defined safety position when compressed air is exhausted, achieving certifications for use in safety-related control systems up to SIL 2 in low demand mode and SIL 3 in a redundant architecture.

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.

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.
