Proportional 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. Advanced electro-hydraulic proportional valves designed for continuous, high-precision electronic control of flow velocity, actuator direction, and system pressure. Direct replacement for Rexroth proportional directional (4WRA, 4WRE, 4WRZ), proportional pressure (3DREP, DBE, DBEM), and proportional flow control valves (2FRE). Engineered with proportional wet-pin solenoids, hardened valve sleeves, and optional integrated electronics (OBE) accepting standard ±10V or 4-20mA control signals.
