Our ZDHW electric low-flow regulating valve is adaptable to various operating conditions with different flow requirements. Equipped with the PSL series electronic electric actuator, which incorporates a servo amplifier, no additional servo amplifier is needed. It can be controlled with input control signals (4-20mADC or 1-5VDC) and a single-phase power supply, enabling adjustment of flow and other parameters. The electric low-flow regulating valve is a customized electric regulating valve designed for specific operating conditions. The tiny flow electric regulating valve is forged from a forging valve body, making it easy to form a high-pressure structure. The valve core size can range from 0.15-15mm in machining tolerance. The tiny flow electric regulating valve features a small size, light weight, simple wiring, high flow rate, and high adjustment accuracy. It is widely used in industrial process automatic control systems in industries such as power, oil, chemicals, metallurgy, environmental protection, light industry, education, and scientific research equipment.
