Electric Actuator Performance Characteristics
1, Shell - due to the use of high-quality aluminum alloy, light weight. And the inner and outer surfaces are anodized, and the outer surface is coated with polyester powder, and the corrosion resistance is strong. 
2, The motor - using SPG squirrel-cage motor, the output torque is large, and built-in thermal protection switch, the temperature control, to prevent damage to the motor. 
3, Manual structure - no power, pull the clutch handle can be manually operated. When energized, the clutch is automatically reset. 
4, The position indicator - the indicator is installed on the central axis, you can observe the valve position. And the indicator light (SLU) to choose from. 
5, Dryer - used to control the temperature, to prevent the internal condensation of the actuator, to keep the internal electrical components of the dry. 
6, Limit switch - by the cam mechanism to control, a simple adjustment mechanism can accurately and easily set the location. 
7, Torque switch (except HQ-008 outside) - can provide overload protection, to prevent damage to the motor. (Set before the factory is set, please do not change the settings of the user). 
8, Self-locking - a self-locking function to prevent reversal, rotating part of the stable and reliable. 
9, The installation - the bottom of the installation size in line with ISO5211 international standards, drive sleeve can be removed according to the need for processing, strong adaptability. Can be installed vertically or horizontally. 
10, The terminal - the circuit layout is compact and reasonable, the terminal diameter of 2.5mm, pressure, strong connection. 
11, Worm gear - with concave wheel design, and the contact surface with the worm, transmission torque, smooth and wear, long service life.
