Electric actuators

  

Overview

EA (E) series of motor driven executors are the drive devices for loop type electronic valves, capable of performing on/off and angle position control by using exterior power switching or external output signals.

The shell of this device is made up of cast aluminum alloy by the integration of the embedded engine, accurate drive system and shells. It has outstanding performances such as light in weight, with better structure, delicate visual shape, high efficiency and output torque.

Features

1. Small size, light weight, better structure, convenient in operation and installation and can be used at very narrow places

2. Manual operation function: attached cranks can be used for manual operation after power is cut off

3. Decelerating mechanism finally applies high abrasion resistant alloy worm gears with relatively more stable torque

4. Protection function: With overheat protectors in the engine to be able to prevent any damage to the engine in the overload state

5. Servo amplifiers are made up of large scale integrated circuits
