Brand: Festo

Quarter turn actuator DFPD-20-RP-90-RS30-F04

The Festo part number 8047621 is a single-acting gear rack/pinion industrial valve actuator featuring a size of 20, an F04 flange hole pattern, and a 90-degree swivel angle. Operating within a pressure range of 2 bar to 8 bar and a nominal operating pressure of 3 bar, it includes a safety function that switches the unit to a defined safety position via spring force when compressed air is switched off and the spring chamber is exhausted. Certified for safety functions to ISO 13849 and IEC 61508, the component supports up to SIL 2 in low demand mode and SIL 1 in high demand mode, or up to 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.

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.
