Festo
8172155
Linear actuator DFPC-250-300-D-V4EX4-45E-45S-M24P-W2
The Festo 8172155 is a double-acting industrial component featuring a 250 mm piston diameter, a 250 valve actuator size, and a 300 mm stroke. Operating within a pressure range of 2.5 bar to 8 bar (36.25 psi to 116 psi) at a nominal operating pressure of 6 bar (87 psi), this unit incorporates elastic cushioning rings or pads at both ends and utilizes an ISO 5210 standard connection for valves with F10 and F14 flange hole patterns. Designed with a piston, piston rod, tie rod 1, and cylinder barrel structural layout, it supports any mounting position and enables position sensing via proximity switch. Certified for explosive atmospheres with ATEX and UKEX compliance for Zones 1, 2, 21, and 22, this assembly is available with variants including ATEX EX protection approval, special threads, shortened external threads, and extended piston rods.
