Brand: Festo

Quarter turn actuator DFPD-20-RP-90-RS60-F05-R3-C

The Festo part number 8102798 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 20 and a 90-degree swivel angle. Operating at a nominal operating pressure of 0.6 MPa (6 bar / 87 psi) with an operating pressure range of 2 bar to 8 bar (29 psi to 116 psi) and a burst pressure of 24 bar, this safety device incorporates an ISO 5211 standard valve connection and VDI/VDE 3845 NAMUR compliance. The integrated safety function relies on spring force from the spring assembly to switch to the defined safety switching position 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 per ISO 13849 and IEC 61508.

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.
