Brand: Festo

Quarter turn actuator DAPS-0015-090-R-F04-T6

The Festo 553171 is a double-acting industrial component featuring a kinematic yoke system with a 0015 valve actuator size and a 90-degree swivel angle. Operating within a pressure range of 0.3 MPa to 0.84 MPa (3 bar to 8.4 bar) at a nominal operating pressure of 0.56 MPa (5.6 bar), this unit utilizes an F04 flange hole pattern, a 13.2 mm shaft connection depth, and an ISO 5211 standard valve connection that conforms to VDI/VDE 3845 (NAMUR). It offers a 1 Hz maximum swivel frequency at 6 bar, an end-position adjusting range of -1 degrees to 9 degrees at 0 degrees, closes to the right without cushioning, and includes ATEX and UKCA markings for explosion protection in ATEX Zones 1, 2, 21, and 22 up to SIL 2 low demand mode.

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.
