Brand: Festo

Quarter turn actuator DAPS-1920-090-RS1-F16

The Festo part number 549689 is a single-acting industrial component featuring a size 1920 valve actuator with an F16 flange hole pattern and a kinematic yoke system structural design. Operating within a pressure range of 2.8 bar to 8.4 bar at a nominal operating pressure of 5.6 bar, this unit delivers a 90-degree swivel angle that closes to the right, supported by an ISO 5211 standard valve connection and VDI/VDE 3845 NAMUR compliance. It includes an un-cushioned design with no position sensing, an ATEX-compliant CE marking, safety integrity level (SIL) up to SIL 2 low demand mode, and adjustable end-positions spanning -5 degrees to 5 degrees at 0 degrees and 85 degrees to 95 degrees at the nominal angle.

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.
