Name: Festo 8144441 Quarter turn actuator DFPD-160-RP-90-RS35-F07-17-R3-C-VDE2
Brand: Festo

Quarter turn actuator DFPD-160-RP-90-RS35-F07-17-R3-C-VDE2

The Festo part number 8144441 is a single-acting industrial component featuring a gear rack and pinion structural design with a 160 valve actuator size, an ISO 5211 standard valve connection, and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal operating pressure of 3.5 bar, this safety device incorporates a spring assembly to switch to a defined safety position upon air pressure loss and spring chamber exhaustion. It includes F07 flange hole patterns, a 19 mm shaft connection depth, VDI/VDE 3845 NAMUR valve compatibility, and VDI/VDE 3845 Size AA 1 positioner connections, with functional safety certifications up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in redundant architectures pursuant 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.

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.
