The 4WRLE 10 V55M-3X/G24TK0/A1M valve belongs to the 4WRL Solenoid Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. Designed as a proportional control element, it modulates flow and pressure in NG10 circuits. Electrical actuation uses a ±10 V command value, and the input impedance is 100 kΩ so standard motion controllers can drive the coil without high load. A 24 VDC supply powers the onboard electronics while total consumption stays within 40 VA, supporting compact power supplies. The housing meets IP65, and NBR seals are fitted to tolerate common mineral oils. The valve mounts on an ISO 4401-05-05-0-05 interface, ensuring compatibility with existing subplates. Contamination limits match ISO 4406 18/16/13 to maintain spool accuracy.
In operation, the valve accepts pilot oil through the V symbol path; pilot flow reaches 4.5 l/min, and with zero command the main stage permits only 1.7 l/min to reduce internal leakage. The pilot section requires a minimum of 10 bar to shift the spool reliably. Ports A, B, and P accommodate 350 bar when an external supply is used, whereas an internal supply limits these same paths to 280 bar. Port X is likewise rated for 280 bar, and return ports T and y withstand 250 bar. Together these pressure limits allow the valve to control medium-pressure actuators while maintaining safe margins across service lines.
