High Frequency Proportional Directional Valve

Supplied by Huafilter with direct factory sourcing from Beijing Huade Hydraulic—whose manufacturing foundations stem from long-term technical cooperation and joint ventures with Rexroth since 1979. High-response proportional servo valves engineered for high-frequency dynamic closed-loop positioning, velocity, and force control. Direct functional equivalent to Rexroth 4WRPEH 6-3X and 4WRPEH 10-3X series. Equipped with linear position transducers (LVDT), sub-zero overlap spools, and onboard analog electronics. Delivers cutoff frequencies up to 70 Hz at -3dB, providing millisecond-level responsiveness for test benches and CNC hydraulic press machines.
