Linear actuator offers robust and exact process control

The DFPI combines the functions of a linear actuator, a positioner and displacement encoder in one easy to install unit. As a result, Festo says users can increase operational efficiencies as well as cut the time and costs associated with specifying and installing equipment. "The DFPI actuator with integrated positioner is the most resistant solution available for dust and aggressive environments in the process automation markets" said the company's product manager Steve Sands. "We can now supply both entry level equipment and more advanced positioned actuators, in each case tailored to the customer's application." The DFPI unit is delivered with fittings and connectors pre-assembled, together with the electrical cable and two pneumatic tubes for the power supply and exhaust inside a flexible protective conduit. It is available in a variety of diameters (100, 125, 160, 200, 250 and 320mm) and strokes from 40mm up to 990mm. Special designs above 990mm stroke are also available on request.
