Festo
549688
Quarter turn actuator DAPS-1440-090-RS4-F16
This Festo industrial component, part number 549688, is a single-acting valve actuator featuring a size of 1440, an F16 flange hole pattern, and a kinematic yoke system with a 90-degree swivel angle. It operates at a nominal pressure of 0.56 MPa (5.6 bar) with an operating pressure range of 0.56 MPa to 0.84 MPa, provides a maximum swivel frequency of 1 Hz at 6 bar, and includes ATEX CE marking along with SIL 2 low demand mode safety integrity level compliance. The unit incorporates an un-cushioned design with a 49.5 mm shaft connection depth, ISO 5211 standard valve connection, VDI/VDE 3845 NAMUR conformity, and adjustable end-positions spanning -5 to 5 degrees at 0 degrees and 85 to 95 degrees at the nominal swivel angle.
