Festo
8141421
Linear actuator DFPC-320- -
The Festo part number 8141421 is a double-acting industrial component featuring a 320 mm piston diameter, an actuator size of 320, and a stroke length ranging from 10 mm to 1600 mm with an ISO 5210 standard valve connection and F10 or F14 flange hole patterns. This unit incorporates elastic cushioning rings or pads at both ends, operates within a pressure range of 0.25 MPa to 0.8 MPa (2.5 bar to 8 bar or 36.25 psi to 116 psi) with a nominal operating pressure of 0.6 MPa (6 bar), and utilizes a structural design comprising a piston, piston rod, tie rod 1, and cylinder barrel with position sensing via proximity switch. Certified for explosive environments in ATEX Zone 1, Zone 2, Zone 21, and Zone 22 as well as UKEX Zone 1 and Zone 21, the assembly carries ATEX category gas II 2G ratings with CE and UKCA markings alongside EPL Gb (GB) and EPL Db (GB) explosion protection certifications outside the EU.
