Brand: Festo

Quarter turn actuator DFPD-40-RP-90-RS30-F04-R3-EP

The Festo 8047642 is a single-acting industrial valve actuator featuring a gear rack and pinion structural design with a size 40 valve actuator and an F04 flange hole pattern. It provides a 90-degree swivel angle with an end-position adjusting range of -5 degrees to 5 degrees at both 0 degrees and the nominal swivel angle, operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal operating pressure of 3 bar (43.5 psi). Certified as a safety device to ISO 13849 and IEC 61508, the safety function utilizes spring force to switch to the defined safety switching position upon compressed air exhaust, supporting safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in 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.
