The 4WRSE6V20-3X/G24K0/A1V valve is manufactured by Bosch Rexroth within the 4WRSE High Response Control Valves series for precise hydraulic automation. A supply voltage of 24 VDC powers the internal electronics so the proportional solenoid can be driven directly. The command value input accepts a ±10 V signal, while a ±10 V actual value signal limited to 2 mA returns spool position for closed-loop control. Solenoid current can reach 2 A to obtain rapid flow changes, and continuous operation is supported by a 100 % duty cycle. Connection is made through a plug that conforms to DIN EN 175201-804, and an IP65 housing prevents dust ingress and low-pressure water entry.
The valve withstands operating pressures up to 315 bar, permitting use in medium-pressure hydraulic power units. A maximum flow of 80 l/min defines the upper design limit, while a nominal flow of 20 l/min at Δp 10 bar serves as a sizing reference. Mounting follows the ISO 4401-03-02-0-94 port pattern, and sealing to the subplate uses an R-ring measuring 9.81 × 1.5 × 1.78. All dynamic seals are made from FKM for resistance to common hydraulic fluids. System cleanliness must meet ISO 4406 (c) 18/16/13 to protect the internal pilot stage, and the unit’s 3.0 kg weight allows straightforward manual installation.
