The 4WRTE16E125L-4X/6EG24K31/A5M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and guides hydraulic flow in automated machinery. Its size 16 body determines the passage area available for process oil, while the ISO 4401-07-07-0-05 mounting interface lets the unit bolt onto standard subplates. A recommended flow of 460 l/min supports large-volume actuators without excessive pressure drop, and a maximum operating pressure of 350 bar on ports P, A, and B permits use in high-pressure systems. The pilot stage draws 14 l/min at 315 bar so spool shifts occur quickly, and an external return line can tolerate up to 250 bar, whereas the internal T port return must stay below 10 bar to protect the pilot section.
The onboard electronics run from a nominal 24 V DC supply; maximum power demand is 72 VA, giving control panel designers a clear allowance for power distribution. Continuous current is limited to 1.6 A to keep coil temperature within safe limits, yet a 2.7 A impulse current is available for rapid energizing when the valve is commanded. Residual ripple must not exceed 2.5 Vpp so voltage fluctuations do not disturb proportional control accuracy. Connection is made through a DIN EN 175201-804 plug, and two PNP position-switch outputs send end-position signals to the supervisory controller. The housing meets IP65, shielding internal parts from dust and low-pressure water, and the assembly weighs 11.2 kg, a factor considered when sizing the manifold or mounting bracket.
