The 4WREE 10 WA50-2X is a direct-operated proportional directional valve from Bosch Rexroth with integrated on-board electronics (OBE) and electrical position feedback . Here's the breakdown: ⚙️ Model Code Breakdown Code Meaning 4WREE 4 main ports; proportional directional valve with integrated electronics (OBE) and electrical position feedback 10 NG10 (CETOP 5 / ISO 4401-05-04-0-05) W Spool symbol W (4/3-way) A Special characteristic of the WA spool symbol: In neutral, ports A and B are connected to T with approx. 3% of nominal cross-section 50 50 L/min nominal flow 2X Component series 20...29 (installation dimensions unchanged) ⚙️ Key Specifications Parameter Value Max. Operating Pressure 315 bar Max. Flow 180 L/min Nominal Flow 50 L/min Supply Voltage 24 VDC Command Signal 0 to 10V or 4 to 20mA Electrical Connection 7-pin connector (6+PE) per EN 175201-804 Mounting Pattern ISO 4401-05-04-0-05 (NFPA D05) Seals FKM (Viton) for wide fluid compatibility Weight ~4.9 kg ⚙️ Design & Operation · Direct operated with proportional solenoids · Spring-centered control spool returns to neutral when de-energized · Integrated electronics eliminate the need for a separate amplifier module · Electrical position feedback provides high accuracy and responsiveness · Progressive flow characteristics through orifice-type cross-sections ⚠️ Critical Design Considerations · Tank line must not run empty – install a preload valve (approx. 2 bar) in the return line to ensure proper control characteristics · Internal leakage is inherent to the design and may increase over the life cycle · PG fitting adjustment must not be opened as mechanical adjustment below it damages the valve Typical Applications · Industrial hydraulics (presses, machine tools) · Automation systems requiring precise flow/direction control · Closed-loop hydraulic control circuits
