PRODUCT OVERVIEW
Electronic electric high temperature regulating valve is composed of intelligent integrated actuator and high-precision low flow resistance regulating valve body. The electric high temperature regulating valve has the advantages of tight closing, compact structure, light weight and convenient maintenance. It is equipped with 3810 series (or PSL Series) electric actuator and fine and small regulating valve body, with feeding function. It receives the unified standard signal of 4-20mA or 1-5V · DC, converts the current signal into the corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve the continuous adjustment of process parameters such as pressure, flow, temperature and liquid level of fluid in the pipeline. The regulating mechanism of the electric high temperature regulating valve adopts the balanced valve plug structure. The electronic electric high temperature regulating valve has the characteristics of good valve stability, not easy to vibrate, low noise, low temperature sensitivity, small allowable pressure difference and large temperature. It is widely used in occasions with large flow, high temperature and lax leakage requirements.
