The 4WRSE10E50-3X/G24K0/A1V valve belongs to the 4WRSE High Response Control Valves series produced by Bosch Rexroth for precise hydraulic automation where fast spool movement and stable flow are required. It accepts a command signal of ±10 V so the drive electronics can issue symmetrical proportional references to the pilot stage. The actual value output is ±10 V with a 2 mA limit, providing feedback for closed-loop controllers without overloading their analog inputs. A 24 VDC supply powers the onboard electronics and solenoids, and an input resistance above 50 kΩ reduces loading on the control card. The valve can run at a 100 % duty cycle for continuous service, while a 4 A impulse current accelerates the spool during rapid changes. During steady operation it draws a maximum of 2.8 A, limiting cabinet power requirements. Hysteresis is kept at or below 0.05 %, supporting highly repeatable flow near the neutral position.
The unit tolerates operating pressures up to 315 bar, enabling use in high-pressure manifolds found in presses and molding machines. A nominal flow of 50 l/min at a 10 bar differential defines standard cylinder speed, and the valve can pass up to 180 l/min when fast traverse is needed. The ISO 4401-05-04-0-94 porting pattern matches common subplates so installation does not require special machining. IP65 protection shields the electronics from dust and water jets, and FKM seals withstand aggressive hydraulic fluids. The assembly weighs 7.3 kg, allowing direct manifold mounting without extra supports. Zero-point drift remains below 0.3 % per 100 bar, maintaining a stable neutral position as system pressure varies.
