1. Enclosure: The enclosure is made of hard aluminum alloy, anodized and polyester powder coated, with strong corrosion resistance, the protection level is IP67, and IP68 and explosion-proof types are available.
2. Motor: Fully enclosed squirrel-cage motor, small size, large torque, low inertia force, insulation class F, built-in overheat protection switch, which can prevent overheating and damage to the motor.
3. Manual structure: The design of the handwheel ensures reliability, labor saving and small size. When the power is not turned on, the clutch handle can be manually operated. When the power is turned on, the clutch automatically resets.
4. Indicator: The indicator is installed on the central axis, and the position of the valve can be observed. The mirror surface is designed with a convex lens, which does not accumulate water and is more convenient to observe.
5. Dryer: used to control the temperature, prevent moisture condensation inside the actuator due to temperature and weather changes, and keep the internal electrical components dry.
6. Limit switch: mechanical and electronic double limit. The mechanical limit screw is adjustable, the electronic limit switch is controlled by the cam mechanism, and the simple adjustment mechanism can accurately and conveniently set the position without battery support.
7. Torque switch: It can provide overload protection. When the valve is stuck and there is foreign matter, it will automatically disconnect the motor power supply, which can more effectively protect the valve from damage.
8. Self-locking: Precise double worm gear mechanism can efficiently transmit large torque, high efficiency, low noise, long life, self-locking function, prevent reverse rotation, stable and reliable transmission part, has been filled with high-efficiency grease at the factory, no need to use it again. come on.
9. Anti-dropping bolts: When the shell is removed, the bolts are attached to the shell and will not fall off. The external bolts are made of stainless steel.
10. Digital display of valve position: During the opening or closing process of the electric actuator, the change of valve position is displayed in real time in large numbers on the LCD screen.
