Electro- Thermal Actuator Electric actuator, also known as electric constant temperature controller, is a new concept device used for remote control of system flow and heat (cooling). It is suitable for temperature control of heating and central air conditioning in residential, shopping malls, and hotels, as well as room temperature control. Electric actuators are mainly used in underfloor heating systems to control the closing and opening of pipelines. Specifically applied to the electric drive part of electric actuators for branch valves, small valves, and dynamically balanced v
