The 4WRTE32V600L-4X/6EG24K31/A1M valve is a member of the 4WRTE Directional Control Valves series manufactured by Bosch Rexroth for proportional flow and direction control in hydraulic automation. Its valve size 32 establishes large internal flow passages, while a rated flow of 600 l/min at a 5 bar differential supports high-speed cylinder or motor circuits. The spool has a linear flow characteristic so output volume responds directly to command stroke, simplifying closed-loop tuning. A maximum operating pressure of 350 bar allows installation in heavy-duty presses or mobile drives. The ISO 4401-10-09-0-05 mounting interface aligns with standard sub-plates, reducing manifold machining. Protection class IP65 shields the electrical section from dust and water spray, enabling field mounting. With a weight of 31.5 kg the manifold and support hardware must be sized for safe handling.
The electronics on the valve run from a nominal 24 V DC supply; they draw up to 1.6 A so cables and fusing must accommodate a peak power demand of 72 VA. A ±10 V command signal interfaces with typical motion controllers and drives the V-symbol spool that defines the metering overlap chosen for this model. Spool movement is generated by a NG6 6E pilot control valve, and because the pilot oil supply is external the main stage is isolated from fluctuations in system pressure. Return flow from the pilot stage exits through external Port Y, preventing back pressure from influencing control accuracy; Port T on the manifold can be loaded to 250 bar without damaging the unit. These features combine to provide repeatable flow control in closed-loop hydraulic axes where precise positioning and high dynamic response are required.
