Electric High Temperature Control Valve is an industrial automation control device composed of an intelligent integrated actuator and a high-precision low-flow-resistance control valve body. The valve is suitable for operating conditions with large flow, high temperature, and less stringent leakage requirements. Its regulating mechanism uses a balanced valve plug structure, featuring good valve stability, resistance to vibration, and low noise. It has low sensitivity to temperature changes and allows for use in high-temperature but low-pressure differential conditions. It is widely used in high-temperature medium flow regulation systems in industries such as power, metallurgy, chemical, petroleum, and light textile.
