Product Details

Product Overview

The electronic electric high-temperature control valve composed of an intelligent integrated actuator and a high-precision low flow resistance regulating valve body. This valve has the advantages of tight closure, compact structure, light weight, and convenient maintenance. Equipped with a 3810 series (or PSL series) electric actuator and a precision smallcontrolvalve body, it contains a feeding function and accepts a unified 4-20mA or 1-5V · DC standard signal. It 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, temperature, and liquid level of the fluid in the pipeline. The regulating mechanism adopts a balanced valve plug structure, which has the characteristics of good valve stability, low vibration, low noise, low temperature sensitivity, small allowable pressure difference, and high temperature. Widely used in situations with high flow rates, high temperatures, and less stringent leakage requirements.
