Electronic controls for proportional valves

    Electronic drivers manage the power supply and control of proportional solenoids, translating the command signal into regulated current with ramps, dither frequency and integrated diagnostics. Compatible with the main analogue signal formats and industrial communication interfaces, they integrate into any control architecture.

    The range includes Huade-branded series.

    Electronic driver for proportional valves – open loop - HD-US-DAS2 Series

    The HD-US-DAS2 driver manages two independent solenoids with adjustable current up to 3 A per channel, separately configurable rise and fall ramps, and dither frequency from 50 to 450 Hz.

    Selection guide

    What an electronic driver does for a proportional valve

    A proportional solenoid needs a regulated current, not a simple on/off voltage. The electronic driver turns the command signal (±10 V, 0–10 V, 4–20 mA) into that current and adds the functions that make the valve smooth: rise and fall ramps, dither to reduce hysteresis, minimum and maximum current.

    The HD-US-DAS2 drives two solenoids up to 3 A per channel, supply 8–32 VDC, with RS485 connection. Use it with open-loop proportional valves such as the HD-2FRE (flow) or the HD-(Z)DBE(E) (pressure) when the valve does not have integrated electronics.
