Brand: Festo

Quarter turn actuator DFPD-300-RP-90-RS60-F0710

The Festo part number 8048140 is a single-acting gear rack and pinion industrial valve actuator featuring a size 300 actuator, a 90-degree swivel angle, and an operating pressure range of 2 bar to 8 bar (29 psi to 116 psi) with a nominal operating pressure of 6 bar (87 psi). Designed as a safety device conforming to VDMA 66413, it utilizes spring force to switch to a defined safety position when compressed air is switched off and the spring chamber is exhausted, achieving functional safety ratings up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture per IEC 61508 and ISO 13849. The unit includes an F0710 flange hole pattern, a 24 mm shaft connection depth, ISO 5211 standard valve connection, VDI/VDE 3845 NAMUR valve connection, and VDI/VDE 3845 Size AA 2 positioner and position sensor connection points, supporting any mounting position, right-closing direction, and end-position adjusting ranges of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle.

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.
