The 4WRAE10EA30-2X/G24N9K31/A1V valve is manufactured by Bosch Rexroth as part of the 4WRA Proportional Directional Valves series and is intended to regulate flow and direction in hydraulic automation circuits. It is energized by a 24 VDC supply, and the ±10 V command value range gives the controller a symmetrical window for spool positioning. A minimum input resistance of 100 kΩ keeps load on the signal source low, while a maximum current draw of 1.2 A limits the burden on the power supply. Short switching events are covered by a 2.7 A impulse current, and overall power consumption does not exceed 24 VA. The residual ripple must stay below 2.5 Vpp so the solenoid does not exhibit unintended motion. Electrical hookup is made through a 6-pole plus protective-earth connector in accordance with DIN 43563, and cable runs of up to 40 m are supported when liycy 7×1.0 mm² conductors are used. An external 4 A time-lag fuse is specified to protect the supply path against overcurrent.
The housing carries an IP65 rating so the valve can be installed in areas exposed to dust and water spray without additional enclosures. Operation is permitted in ambient temperatures up to 60 °C, and the hydraulic fluid may reach 70 °C without compromising internal components. System planners must maintain oil cleanliness at ISO 4406 20/18/15 to preserve spool accuracy and service life. FKM seals are fitted to resist common hydraulic media and elevated temperatures found in industrial machines. A mean time to dangerous failure of 150 years highlights the valve’s reliability in safety-related applications.
