Brand: Festo

Quarter turn actuator DAPS-1920-090-R-F1216-T6

The Festo part number 553187 is a double-acting industrial component featuring a kinematic yoke system with a size 1920 valve actuator, a 90-degree swivel angle, and an end-position adjusting range at 0 degrees from -1 to 9 degrees. This un-cushioned unit connects via an ISO 5211 flange hole pattern of F12 or F16, a 48.5 mm shaft connection depth, and a VDI/VDE 3845 NAMUR valve standard, operating at a nominal pressure of 5.6 bar across a 3 bar to 8.4 bar operating pressure range with a maximum swivel frequency of 1 Hz at 6 bar. It offers SIL 2 low demand mode safety integrity, closes to the right without position sensing, accommodates any mounting position, and carries ATEX and UKCA markings for explosion prevention in zones 1, 2, 21, and 22.

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.
