AQTE series compact electric actuator is the rotary force of the motor through the multi-stage reduction gear, worm gear and other mechanisms, and finally through the output shaft, in the form of rotation 90° to switch the valve device, mainly to drive and control the Angle of the valve opening, such as butterfly valve, ball valve, plug valve and other similar valve applications. The output torque range is 50-2500N.m, and the control mode is mainly divided into two categories: switching type and regulating type. The shell of the product is made of die-cast aluminum alloy shell, multi-stage reduction gear, copper alloy worm gear and high strength alloy steel worm transmission structure.
