Electric Actuator
Multi-turn actuators are required for the automation of multi-turn valves. One of the major representatives of this type is the gate valve. “A multi-turn actuator is an actuator which transmits to the valve a torque for at least one full revolution. It is capable of withstanding thrust.”
Part-turn actuators are required for the automation of part-turn valves. Major representatives of this type are butterfly valves and ball valves. “A part-turn actuator is an actuator which transmits a torque to the valve for less than one full revolution. It need not be capable of withstanding thrust.”
