The ZDHW electric small-flow control valve adapts to various operating conditions with differing flow requirements. Equipped with the PSL series electronic electric actuator featuring imported German technology, the electric actuator incorporates a servo amplifier, eliminating the need for an additional servo amplifier. It operates with input control signals (4–20mADC or 1–5VDC) and single-phase power supply to regulate flow and other parameters. The electric low-flow control valve is a custom-designed electric control valve for specific operating conditions. The micro-flow electric control valve utilizes a forged valve body, facilitating high-pressure construction. Spool sizes range from 0.15 to 15 mm with machining tolerances. This micro-flow electric control valve features a compact size, light weight, simple wiring, high flow capacity, and high regulation accuracy.
