Brand: Festo

Quarter turn actuator DFPD-900-RP-90-RS60-F14

This Festo industrial component features a size 900 single-acting gear rack/pinion valve actuator with an ISO 5211 flange hole pattern, a 90-degree swivel angle, and an operating pressure range of 2 bar to 8 bar. Designed with a NAMUR VDI/VDE 3845 valve connection and a VDI/VDE 3845 Size AA 3 connection point for positioners and sensors, the unit incorporates a safety function that switches the actuator to a defined safety position via spring force when compressed air is removed and the spring chamber is exhausted. Certified to ISO 13849 and IEC 61508 for functional safety, it supports safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture for safety-related control system parts.

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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

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.
