1、 Overview of Electric High Temperature Regulating Valve Products
The electric high-temperature regulating valve of Shanghai Yuhu Company is composed of an intelligent integrated actuator and a high-precision low flow resistance regulating valve body. Electric high-temperature regulating valves have the advantages of tight closure, compact structure, light weight, and easy maintenance. The electric high-temperature regulating valve is composed of a 3810 series (or PSL series) electric actuator and a compact regulating valve body, which includes feeding function. It accepts a unified 4-20mA or 1-5V · DC standard signal, converts the current signal into a corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve continuous adjustment of process parameters such as pressure, flow rate, temperature, and liquid level of the fluid in the pipeline. The regulating mechanism of the electric high-temperature regulating valve adopts a balanced valve plug structure. The electronic electric high-temperature regulating valve has the characteristics of good valve stability, low vibration, low noise, low sensitivity to temperature, small allowable pressure difference, and high temperature. Electric high-temperature regulating valves are widely used in situations where flow rate is high, temperature is high, and leakage requirements are not strict. Widely used in pipeline automation control of corrosive media such as gases, liquids, vapors, and oils.
