Festo
8172157
Linear actuator DFPC-250-400-D-V4EX4-3E-45S-M24P-W2
This double-acting industrial component from Festo features a 250 mm piston diameter, a 400 mm stroke, and a size 250 valve actuator with an ISO 5210 standard valve connection and F10 or F14 flange hole patterns. Operating at a nominal pressure of 0.6 MPa (6 bar / 87 psi) across a 0.25 MPa to 0.8 MPa range, the unit incorporates elastic cushioning rings at both ends and allows position sensing via proximity switch in any mounting position. Certified for Zone 1, Zone 2, Zone 21, and Zone 22 hazardous areas under ATEX and UKEX directives with II 2G and II 2D categories, the assembly utilizes a structural design comprising a piston, piston rod, tie rod 1, and cylinder barrel, with configurable variants including ATEX EX protection, special or shortened threads, and extended piston rods.
