Electronic single seat control valve

Electronic electric single seat regulating valve, consisting of electronic electric actuator and single seat valve, is suitable for small pressure differential conditions. Electric actuator built-in servo system, no need to match the servo amplifier, input signal and power supply can control the operation. The structure is compact, the fluid channel is S streamline. It has the advantages of small volume, light weight, low pressure drop, large flow, wide adjustable range and high accuracy of flow characteristics. The application of precise control of minute traffic. Such as fine chemical, food additive, medical flower, electronic industry.
