Linear actuatorLinear actuators from Festo are double-acting pneumatic piston actuators. The sturdy, corrosion-resistant design of the actuators is ideal for use in harsh and explosive ambient conditions in process automation applications. Actuators with different diameters, stroke lengths and standardised mounting interfaces are available for different installation situations. The linear actuators are suitable for opening/closing and control applications. Special product versions with an integrated displacement encoder or fully integrated positioner are available for control applications. Applications for linear actuators can be found in numerous industrial segments of process automation, such as linear movements for process valves (knife gate valves, shut-off valves, dosing slides, pinch valves) or swivel movements for damper control (ventilation flaps, turbine blade adjustment, etc.).
