Quarter turn actuator DFPD-N-300-RP-90-RS35-F10-R3-C

The Festo industrial component, part number 8102854, is a single-acting gear rack and pinion valve actuator featuring a size of 300, an ISO 5211 standard valve connection, and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar and a burst pressure of 24 bar, this safety device achieves its closing direction to the right and executes its safety function via spring force when compressed air is switched off and the spring chamber is exhausted. Certified to ISO 13849 and IEC 61508, the unit supports up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture, with a VDI/VDE 3845 NAMUR valve connection and VDI/VDE 3845 Size AA 2 positioner interface.

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.
