The electric control valve is often used in pipelines for conveying hot water and high-temperature steam. The electric actuator is connected to the valve body through a support rod, and the support rod is generally made of metal material. Due to heat conduction and radiation, heat will be transferred to the motor and electronic control device inside the electric actuator through the support rod, resulting in an increase in the temperature of internal components. Therefore, it will cause damage to the electric actuator and the problem of failure of the control function.
