Electric actuators are rotary actuators for control valves, ball valves, butterfly valves and other valves.
The electric actuators come in many versions, which are subdivided according to the way of rotation or driving. The most standard electric motor is the 90° motor, which is used for valves such as the ball valve and butterfly valve. Another variant on the 90° motor is the spring return motor, which also rotates 90°, and is only driven in one direction by a fail-safe spring. In addition to the 90° actuators, there are also the linear actuators. These actuators drive an axis in linear motion. A comprehensive variant of the linear electric motor is a multi-turn actuator. The Multi-turn motor is a smart actuator which is used for valves such as knife edge valves.
