4WRZE16W6-100-7X/6EG24K31/A1D3M

The 4WRZE16W6-100-7X/6EG24K31/A1D3M proportional directional valve belongs to the WRZ Proportional Directional Valves series from Bosch Rexroth and is installed to meter and switch hydraulic flow in automated machinery. It is produced in size 16, a dimensional code that defines mounting interface and spool capacity. At a differential pressure of 10 bar it delivers a nominal flow of 100 l/min, giving predictable actuator speed during standard cycles. When the spool is driven to its end position the main passage admits up to 460 l/min, so the same unit can serve fast traverse requirements without replacement. The hydraulic envelope tolerates 350 bar on the pressure ports, enabling use in high-force systems, while the return line can accept 250 bar back pressure so remote accumulators or long hoses do not force derating. Continuous energization is supported by a 100 percent duty cycle rating, which allows the valve to hold position commands indefinitely without thermal shutdown.

Electrical integration starts with a 24 V DC supply that powers the internal amplifier and position feedback loop. Motion controllers issue a ±10 V command signal, and the electronics convert this reference into proportional solenoid current to position the spool. The copper winding shows 2 Ω resistance at 20 °C, a value that defines inrush behavior and simplifies fuse selection. During normal modulation the amplifier draws no more than 1.8 A, staying within common power-distribution limits for cabinet supplies. Peak demand can rise to 2.5 A when the spool is driven rapidly, so wiring and drivers must accommodate that short-term load. These electrical figures complement the hydraulic performance presented earlier and confirm that the 4WRZE16W6-100-7X/6EG24K31/A1D3M integrates readily into closed-loop servo systems where precise flow control and repeatable response are required.
