Festo’s DFPC double acting linear actuator optimized for process applications. It’s available in either standard, preconfigured versions.
The latter can be ordered with different stroke lengths of the space bolts, piston rods of differing lengths, different thread types and diameters, even adapted for ATEX II 2GD certification.
DFPC has been designed for actuating process valves types such as gate, knife-gate and pinch valves, or valve bodies without housing. It’s ideal, for example, for the demanding requirements in water- and waste-water treatment, the mining industry, power stations as well as the paper, pulp and steel industries.
The piston rods, screws, nuts and tie rods are made of stainless steel, while the cylinder barrels and end caps are made of aluminum.
There are interfaces for process valve to ISO 5210 and ISO 15552 with extended tie rods. Proximity switches, mountings for position sensing and Namur adapter plate are available as accessories. The DFPC is available currently with strokes of up to 1600 mm and in the sizes 80 to 200.
