Festo
8172146
Linear actuator DFPC-100-80-D-V4EX4-44E-9S-W2
The Festo 8172146 is a double-acting industrial component featuring a 100 mm piston diameter, an 80 mm stroke, and an ISO 5210 standard connection for valves with an F07 flange hole pattern. Operating within a pressure range of 0.2 MPa to 0.8 MPa (2 bar to 8 bar / 29 psi to 116 psi) at a nominal pressure of 0.6 MPa (6 bar / 87 psi), this piston-and-tie-rod assembly incorporates elastic cushioning rings at both ends and enables position sensing via proximity switch. Certified for explosive atmospheres with ATEX, UKEX, and EPL Gb/Db approvals for Gas Zone 1 and Dust Zone 21, the unit supports any mounting position alongside customizable variant options including extended or shortened external threaded piston rods.
