Name: Festo 8144437 Quarter turn actuator DFPD-160-RP-90-RS60-F07-17-R3-C
Brand: Festo

Quarter turn actuator DFPD-160-RP-90-RS60-F07-17-R3-C

The Festo 8144437 single-acting industrial component features a gear rack and pinion structural design with a 160 valve actuator size, a 90-degree swivel angle, and an F07 flange hole pattern. Certified for safety functions to ISO 13849 and IEC 61508, this safety device achieves its defined safety switching position through spring force when compressed air is switched off and the spring chamber is exhausted. It operates within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal operating pressure of 6 bar, with compatibility for VDI/VDE 3845 valve connections and positioners.

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.
