Brand: Festo

Quarter turn actuator DFPD-300-RP-90-RS30-F0710

The Festo part number 8048139 is a single-acting gear rack/pinion industrial valve actuator with a size of 300 and a 90-degree swivel angle. Featuring an ISO 5211 standard valve connection and VDI/VDE 3845 NAMUR compliance, this component operates at a nominal pressure of 3 bar (43.5 psi) within an operating pressure range of 2 bar to 8 bar (29 psi to 116 psi) and includes 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 for safety functions to ISO 13849 and IEC 61508, the unit 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.

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.
