Angular stroke actuator is an electric actuator, which is specially used to control the rotation angle. It usually consists of a motor, transmission mechanism, control circuit and casing. This type of actuator can be used to control rotating equipment such as dampers, valves, deflectors and fans.

Compared with traditional pneumatic or manual control, Angular stroke actuator has many advantages, such as higher accuracy, wider control range, programmability, automation and remote control, etc. They are commonly used in areas such as smart buildings, industrial automation, robotics, aerospace and the automotive industry.
