The 4WRZ10E1-85-7X/6EG24ETK4/D3V belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and is intended to meter hydraulic flow and direction in automated circuits. It runs from a 24 V DC supply through a DIN EN 175301-803 plug, simplifying electrical integration. A 100 % duty cycle allows the solenoid to remain energized continuously. Hysteresis does not exceed 6 %, giving stable spool feedback when command signals vary. The coil withstands temperatures up to 150 °C, preventing thermal damage in high-heat environments. FKM seals contain leakage while resisting mineral oil and temperature cycling. Internal pilot supply and drain eliminate external pilot lines. A 1.8 mm throttle insert and a 3.5 l/min pilot oil flow support full stroke operation across the control range.
The main stage endures operating pressures to 315 bar, making the valve suitable for high-pressure manifolds. Return pressure at port T can reach 30 bar without affecting function. Maximum flow capacity is 170 l/min, while nominal flow is 85 l/min at a 10 bar differential, establishing sizing data for system designers. Mineral oils of type HL or HLP under DIN 51524 are the recommended media for lubrication and wear control. Fluid entering the main gallery should meet ISO 4406 cleanliness class 20/18/15, and the pilot gallery should reach class 18/16/13 to protect small orifices. These cleanliness targets ensure proportional response and long service life. Together, pressure capability, flow range, and oil requirements make this valve dependable for precise, continuous directional control in hydraulic automation.
