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

The Festo 8102852 is a single-acting gear rack/pinion industrial component featuring a valve actuator size of 300, an F10 flange hole pattern, a 90-degree swivel angle, and a 24 mm shaft connection depth. Operating between 2 bar and 8 bar (29 psi to 116 psi) with a nominal operating pressure of 4.5 bar (65.25 psi) and a burst pressure of 24 bar, this safety device achieves its safety function via spring force when compressed air is switched off and the spring chamber is exhausted, supporting safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture according to ISO 13849 and IEC 61508. It includes adjustable end-positions from -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle, features standard valve connections conforming to ISO 5211 and VDI/VDE 3845 (NAMUR), closes to the right, allows any mounting position, and incorporates a connection point for positioners and position sensors conforming to VDI/VDE 3845 Size AA 2.

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.
