Overview
Micro flow electric control valves have the characteristics of small size, light weight, simple connection, high flow rate, and high adjustment accuracy. They are widely used in industrial process automatic control systems in industries such as power, petroleum, chemical, metallurgy, environmental protection, light industry, teaching and research equipment.
Product Details
Imported electric small flow regulating valve
The imported electric small flow control valve from Germany's Ward WODE is a customized electric control valve for certain special working conditions. The small flow electric control valve is forged with a forged valve body, which is easy to make into a high-pressure electric control valve. The size of the valve core can vary from 0.15-15mm due to machining differences, and can adapt to various working conditions with different flow requirements. Equipped with Ward's intelligent high-precision actuator, the electric actuator has a servo amplifier inside, which does not require additional servo amplifiers. It can be controlled by input control signals (4-20mADC or 1-5VDC) and single-phase power supply to adjust flow and other parameters. Micro flow electric control valves have the characteristics of small size, light weight, simple connection, high flow rate, and high adjustment accuracy. They are widely used in industrial process automatic control systems in industries such as power, petroleum, chemical, metallurgy, environmental protection, light industry, teaching and research equipment.
