Rexroth BOSCH Proportional Directional Valve – Type 4WREE 6 E1-08-2X · 模型 48357
This is a direct-operated proportional directional valve with electrical position feedback from Bosch Rexroth's 4WREE series, designed for precise control of oil flow direction and size in industrial hydraulic systems . The valve requires external electronics (not integrated) to control its proportional solenoids . Model Code Breakdown (4WRE-6-E1-08-2X): Code Meaning 4WRE 4 main ports; proportional directional valve with electrical position feedback; requires external control electronics 6 Nominal size NG6 (CETOP 03 / ISO 4401-03-02-0-05) E1 Spool symbol (standard 4/3-way, closed in neutral; all ports blocked when de-energized) 08 Nominal flow of 8 L/min (at Δp = 10 bar per control edge) 2X Component series 20...29 (installation and connection dimensions remain unchanged) Key Specifications: Parameter Value Max. Operating Pressure 315 bar Max. Flow 80 L/min (NG6 practical limit) Supply Voltage 24 VDC Seals FKM (Viton) as indicated by "/V" in full order code Weight ~2.2 kg Design & Operation: · Direct operated with proportional solenoids (central thread, detachable coil) · Spring-centered control spool returns to neutral when de-energized · Electrical position feedback provides high accuracy and responsiveness · Progressive flow characteristics through orifice-type cross-sections Critical Design Considerations: · External electronics required – must use a separate amplifier module · Tank line must not run empty – install a preload valve (approx. 2 bar) in the return line · Internal leakage is inherent to the design and may increase over the life cycle Typical Applications: · Industrial hydraulics (presses, machine tools) · Automation systems requiring precise flow/direction control · Closed-loop hydraulic control circuits All designs are original engineering work.
