The 4WRTE25Q2-350L-4X/6EG24K31/A5WB16M directional control valve is produced by Bosch Rexroth within the 4WRTE Directional Control Valves series and regulates hydraulic flow and direction in automated machinery. It operates on a nominal supply voltage of 24 VDC, while the electronics tolerate up to 35 VDC without damage. The solenoid draws a maximum of 1.6 A, so power supplies can be sized accordingly. Input resistance is 100 kΩ, minimizing the load that command electronics place on the valve. A 100 % duty cycle allows continuous energization for long process cycles. During peak actuation the coil consumes 72 VA, a figure used to calculate enclosure heat dissipation. The winding endures temperatures up to 150 °C, helping the unit withstand high ambient heat and rapid cycling.
The valve accepts operating pressures to 350 bar on P, A, and B ports, making it suitable for high-pressure hydraulic circuits. At a 5 bar differential across the control edge it meters 350 l/min, and systems may route up to the recommended maximum of 870 l/min when precision demands are lower. The pilot stage requires 20 l/min at 315 bar on X and Y lines, which must be provided by the power unit. Fluid cleanliness must reach ISO 4406 class 18/16/13 to avoid spool wear. Electrical termination is supplied without a mating connector; the interface follows DIN EN 175201-804 for compatibility with standard cord sets. When the plug is correctly mounted the enclosure attains IP65 ingress protection, allowing use in dusty or moist areas. The assembly weighs 16.8 kg, information needed for manifold support and handling equipment.
