1Electric steam regulating valveProduct Description：
electronic typeElectric steam high temperature regulating valveIt is composed of a 3810 series (PSL series) electronic electric actuator and a high-temperature regulating valve body. It consists of a 3810 series (or PSL series) electric actuator and a compact regulating valve body, with feeding and clothing functions. It accepts a unified 4-20mA or 1-5V · DC standard signal, converts the current signal into a corresponding linear displacement, automatically controls the opening of the regulating valve, and achieves 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 electronic 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. Electronic electric high-temperature regulating valves are widely used in situations with high flow rates, high temperatures, and less stringent leakage requirements.
