Name: Festo 8102859 Quarter turn actuator DFPD-300-RP-90-RS60-F10-R3-C-VDE2
Brand: Festo

Quarter turn actuator DFPD-300-RP-90-RS60-F10-R3-C-VDE2

This Festo single-acting industrial component features a gear rack and pinion structural design with a valve actuator size of 300, an F10 flange hole pattern, and a nominal swivel angle of 90 degrees with an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal angle. Certified to ISO 13849 and IEC 61508 for safety functions up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture, the unit operates at a nominal pressure of 6 bar (87 psi) within an operating pressure range of 2 bar to 8 bar (29 psi to 116 psi) and a burst pressure of 24 bar. The safety function utilizes spring force from the spring assembly to switch the actuator to the defined safety position upon air supply removal and spring chamber exhaustion.

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.

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.
