Product overview

Electronic electric single-seat regulating valve is composed of electronic electric actuator and single-seat valve. It is suitable for low pressure difference. The electric actuator has built-in servo system, which can be controlled by input signal and power supply without additional servo amplifier. The structure is compact and the flow passage is S-streamlined. The utility model has the advantages of small volume, light weight, small pressure drop loss, large flow rate, large adjustable range and high accuracy of flow characteristics. The application of precise control of small flow occasions. Such as fine chemicals, food additives, medical flowers, electronics industry.
