Brand: Festo

Quarter turn actuator DAPS-1440-090-R-F12

The Festo 549668 is a double-acting industrial component featuring a kinematic yoke system with a size 1440 valve actuator and an F12 flange hole pattern. Operating at a nominal pressure of 0.56 MPa (5.6 bar) within a 0.1 MPa to 0.84 MPa range, this un-cushioned unit delivers a 90-degree swivel angle with a 0-degree end-position adjusting range from -1 degree to 9 degrees and a maximum swivel frequency of 1 Hz at 6 bar. It incorporates an ISO 5211 standard valve connection, a VDI/VDE 3845 (NAMUR) compliant interface, a 38.5 mm shaft connection depth, right-closing direction, and ATEX/UKCA certifications for explosion protection in Zones 1, 2, 21, and 22 alongside SIL 2 low demand mode capabilities.

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.
