The 4WRZE16E1-100-7X/6EG24N9ETK31/A1D3V proportional directional valve is manufactured by Bosch Rexroth within the WRZ Proportional Directional Valves series. It regulates flow and pressure in hydraulic actuators to support closed-loop automation. The valve delivers a nominal flow of 100 l/min at a 10 bar pressure drop, enabling medium-capacity circuits to move cylinders at consistent speed. A maximum operating pressure of 350 bar allows the unit to function in high-pressure systems without external throttling. The mounting interface follows the ISO 4401-07-06-0-94 pattern so it can be installed on standard subplates. Solenoid power is provided by a 24 V DC supply, and the cold coil presents a resistance of 2 Ω, giving predictable inrush current. Current is limited to 2.5 A to keep the electromagnetic force within the linear control range while accepting a ±10 V command signal from the drive electronics. Continuous modulation is possible because the design supports a 100 % duty cycle.
The coils can reach up to 150 °C without damage, maintaining serviceability in warm manifolds. Environmental sealing reaches IP65 when the mating socket is in place, guarding the electronics against dust and water jets. Electrical connection is made through a DIN EN 175201-804 plug, which aligns with common machine-side harnesses. An integrated pressure-reducing valve stabilizes pilot flow, and both pilot supply and drain are internal, removing the need for extra lines. A concealed manual override permits local actuation during commissioning while avoiding accidental engagement. FKM seals resist mineral oils and many synthetic fluids, extending service life in diverse media. The assembly weighs 13.6 kg, a consideration for manifold support structures and maintenance handling.
