The 4WRTE32Q2-600P-4X/6EG24K31/A1M valve is produced by Bosch Rexroth and belongs to the 4WRTE Directional Control Valves series. It directs hydraulic flow in automated systems by shifting a proportional spool under electronic control. The nominal size of 32 sets the port geometry and enables a rated flow of 600 l/min for high-volume circuits. A maximum operating pressure of 350 bar allows the valve body to work in heavy-duty pressure lines, while the pilot stage functions as long as supply pressure remains between 25 and 315 bar, giving flexibility in pilot source selection. Electrical power is supplied at 24 V DC, and operation continues if the bus drops to 18 V or rises to 35 V, so the electronics tolerate common voltage fluctuations. Peak current draw is limited to 1.6 A, which helps size the driver card and wiring.
The valve delivers a response sensitivity no greater than 0.05 %, so small command changes are converted into precise spool movement. Hysteresis is held below 0.1 %, reducing deviation between forward and reverse strokes in cyclic tasks. The housing is rated IP65, shielding the connector and coils from dust and low-pressure washdown in plant environments. Return flow handled by the external port can be exposed to 250 bar without damage, guarding the unit during load rebounds. Hydraulic oil may vary from −20 °C to 80 °C, enabling cold-start operation and continued service as the system warms. The assembly weighs 31.5 kg, providing mounting rigidity and damping vibration on manifolds or press frames.
