A actuator is an actuator that transfers a torque of less than a full revolution to the process valve. The quarter turn actuators from Festo are tailored specifically to meet the requirements of the process industry in terms of force, corrosion resistance and standardised interfaces. They conform to the standard ISO 5211, which defines the interface between the quarter turn actuator and process valve, and NAMUR VDI/VDE 3845 for the direct mounting of limit switch boxes, positioners and pilot valves. The sturdy, corrosion-resistant design of the actuators is ideal for use in process automation applications in harsh and explosive ambient conditions.
The quarter turn actuators are suitable for opening/closing and control applications for the automation of butterfly valves, ball valves and air dampers. They are also suitable for water/wastewater, beverage, pharmaceutical and general process automation applications.
