Valve electric actuators are divided into two categories: straight stroke and angular stroke. The electric actuator is driven by a power source, and the main circuit is used for controlling the opening and closing of valves, as well as for regulating the flow of pipeline media.

Basic parameters and performance of electric actuators:

1. Control voltage: AC220V, 50/60HZ, DC24V, AC380V, DC220V or other specified voltage.

2. The output torque of the electric actuator can be selected based on the actual torque required when the valve is opened or closed.

3. Switching time of electric actuators: Generally, the opening and closing time of the control valve is between 10-120S, depending on the motor power of the electric actuator.

4. The working current and power of electric actuators: Generally, the higher the motor power, the greater the output torque.

5. Expected endurance value of electric execution: 1500VAC/minute.

6. Limit and protection level of electric actuators: including electrical limit and mechanical limit; Its protection level can reach IP65, and it can reach IP68 under special requirements.

7. The electric actuator can be manually operated, making it easy to control the opening and closing of the valve in case of power failure; Electric actuators can be installed at any angle without being limited by time and space.

8. There are various control methods for electric actuators: a, switch type with source light indication b, switch type with passive contact feedback c, switch type with resistance output d, switch type with valve position feedback (4-20Ma) e, intelligent adjustment type with input and output 4-20Ma

9. Optional accessories for electric actuators: dehumidifier heater, over torque protector.
