The 4WRZ10W6-85-7X/6EG24N9ETK4/D3V valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and regulates flow and direction in hydraulic automation circuits. It delivers a nominal flow of 85 l/min at a 10 bar differential, and the body follows the ISO 4401-05-05-0-94 mounting pattern for straightforward manifold installation. System pressure can reach 315 bar, while a maximum hysteresis of 6 % limits control deviation. The solenoid operates from a 24 V DC supply; coil resistance is 4.8 Ω at 20 °C and current may be driven up to 1.5 A. Continuous operation is supported by a 100 % duty cycle, and the DC designation aligns with mobile and industrial control power standards.
The valve meets cleanliness class ISO 4406 20/18/15, defining the filtration level required for reliable service life. Electrical termination is via a DIN EN 175301-803 connector, and coil insulation handles temperatures to 150 °C during sustained load. Return flow at port T is permitted up to 30 bar without damaging the housing. FKM seals resist common hydraulic media, and the enclosure achieves an IP65 protection rating when the plug is fitted, safeguarding the coil against water jets and dust. Total weight is 7.8 kg, which adds mass damping when the unit is fastened to the machine manifold.
