Brand: Festo

Quarter turn actuator DFPD-900-RP-90-RS35-F14-R3-C

The Festo part number 8102888 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 900 and an F14 flange hole pattern. It provides a 90-degree swivel angle with an end-position adjusting range of -5 deg to 5 deg at both 0 degrees and the nominal swivel angle, alongside a 38 mm shaft connection depth and an ISO 5211 standard valve connection. Operating within a pressure range of 0.2 MPa to 0.8 MPa (2 bar to 8 bar or 29 psi to 116 psi) and a nominal operating pressure of 0.35 MPa (3.5 bar or 50.75 psi), this safety device incorporates a spring assembly to switch to the defined safety switching position upon air exhaustion. It holds SIL ratings up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in redundant architecture, complying with ISO 13849 and IEC 61508 standards for safety functions via VDI/VDE 3845 NAMUR connections and AA 3 positioner interfaces.

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.
