Brand: Festo

Quarter turn actuator DFPD-N-300-RP-90-RS45-F10-R3-C

The Festo 8102855 is a single-acting industrial component featuring a gear rack and pinion structural design with a size 300 valve actuator, an F10 flange hole pattern, and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) and a nominal operating pressure of 4.5 bar (65.25 psi), this safety device closes to the right and incorporates a spring assembly that switches the actuator to a defined safety switching position upon loss of compressed air. It complies with VDI/VDE 3845 for valve and positioner connections, supports safety functions certified to ISO 13849 and IEC 61508 up to SIL 2 in low demand mode and SIL 3 in a redundant architecture, and can be mounted in any position.

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.
