Brand: Festo

Quarter turn actuator DAPS-0480-090-RS3-F14-T6

The Festo 553221 is a single-acting industrial component featuring a kinematic yoke system with a 0480 valve actuator size, an F14 flange hole pattern, and a 90-degree swivel angle that closes to the right. It operates within a pressure range of 0.42 MPa to 0.84 MPa (4.2 bar to 8.4 bar) at a nominal operating pressure of 0.56 MPa (5.6 bar), utilizing a spring force connection pressure of 0.42 MPa (4.2 bar) and achieving a maximum swivel frequency of 1 Hz at 6 bar. This uncushioned unit accommodates an end-position adjusting range from -1 degree to 9 degrees at 0 degrees and 81 degrees to 91 degrees at the nominal angle, provides an ISO 5211 standard valve connection with a 38.5 mm shaft connection depth, conforms to VDI/VDE 3845 (NAMUR) standards, and supports up to SIL 2 low demand mode safety integrity levels for any mounting position without position sensing.

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.
