Brand: Festo

Quarter turn actuator DFPD-40-RP-90-RS30-F0507-R3-EP

The Festo part number 8047629 is a single-acting gear rack/pinion industrial valve actuator featuring a size 40 rating, a 90-degree swivel angle, and an F0507 flange hole pattern. Operating within a pressure range of 2 bar to 8 bar (29 psi to 116 psi) with a burst pressure of 24 bar, this safety device incorporates spring force to switch to a defined safety position when compressed air is removed and the spring chamber is exhausted. It conforms to ISO 5211 for standard valve connections and VDI/VDE 3845 for NAMUR valve connections as well as positioner and position sensor attachment, providing certified functional safety 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.
