The 4WRSE6V1-10-3X/G24K0/A1V valve is produced by Bosch Rexroth as part of the 4WRSE High Response Control Valves series. Designed for hydraulic automation, it modulates flow and pressure to servo cylinders with an input command value signal of ±10 V, allowing direct drive from standard analog motion controllers. The actual value feedback is also ±10 V so the controller can monitor spool position in closed-loop applications. A supply voltage of 24 V DC powers the integrated electronics, and a duty cycle of 100 percent permits continuous operation without cycling off. During normal regulation the electronics draw up to 2 A, while a 4 A impulse load current is available to shift the spool rapidly at start-up. Response sensitivity remains at or below 0.03 percent, and hysteresis does not exceed 0.05 percent, giving stable proportional behavior even with small command changes.
The hydraulic section is rated for a maximum operating pressure of 315 bar, making it suitable for high-pressure circuits. At a differential pressure of 10 bar the nominal flow reaches 10 l/min, while the design can pass up to 80 l/min when higher pressure drop is acceptable, extending its usable range. The porting pattern follows ISO 4401-03-02-0-94 so the valve fits common CETOP 03 subplates without additional machining. An IP65 protection class shields the housing against dust and low-pressure water jets, and FKM seals maintain compatibility with mineral oils and many synthetic fluids. The hydraulic fluid must meet ISO 4406 cleanliness level 18/16/13 to keep the precision spool free of contamination. The unit weighs 3.0 kg, enabling straightforward handling during manifold assembly.
