Brand: Festo

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

The Festo 8144435 is a single-acting industrial component featuring a gear rack and pinion structural design with a size 160 valve actuator, an F07 flange hole pattern, and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar and a nominal operating pressure of 3.5 bar, this safety device incorporates a spring assembly that switches the actuator to the defined safety position when compressed air is switched off and the spring chamber is exhausted. It includes an ISO 5211 standard valve connection, a VDI/VDE 3845 NAMUR valve connection, a 19 mm shaft connection depth, and VDI/VDE 3845 Size AA 1 positioner connections, with certification for safety functions up to SIL 2 in low demand mode, SIL 1 in high 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. 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.

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.
