The 4WRAE10W60-2X/G24N9K31/A1V proportional directional valve is produced by Bosch Rexroth for the 4WRA Proportional Directional Valves series and controls flow direction and rate in hydraulic automation systems. It features a nominal size of 10, and the mounting surface follows ISO 4401-05-04-0-94 for straightforward subplate installation. At a 10 bar pressure drop the spool delivers a nominal flow of 60 l/min, while the channel geometry can pass up to 75 l/min as the maximum permissible flow. Port A, B, and P withstand pressures to 315 bar, with port T limited to 210 bar. Electrical operation uses a 24 V DC supply, and a ±10 V command signal in the A1 configuration positions the spool proportionally. The solenoid may draw up to 2.5 A to achieve full displacement under worst-case hydraulic loading.
An IP65 enclosure rating protects the unit against dust and water jets when the connector is secured. The valve functions in ambient temperatures from −20 to +50 °C, while the hydraulic medium may range from −20 to +80 °C. FKM seals tolerate these temperatures and common fluid chemistries. System cleanliness must reach ISO 4406 code 20/18/15 to maintain spool accuracy. The excitation coil shows a resistance of 2 Ω at 20 °C, a parameter useful for current-controlled drive cards. Power and signal lines terminate through a DIN EN 175201-804 connector, completing the electrical interface for reliable proportional control in industrial or mobile equipment.
