The 4WRZE16W6-100-7X/6EG24K31/A1V proportional directional valve belongs to the WRZ Proportional Directional Valves series and is manufactured by Bosch Rexroth. It meters flow and controls actuator direction in hydraulic automation systems. The valve has a nominal size of 16, and when the differential pressure is 10 bar it delivers a nominal flow of 100 l/min. A maximum operating pressure of 350 bar lets the unit work in high-pressure circuits. The spool type is coded W6, defining overlap and flow gain. Integrated electronics in an OBE module accept a ±10 V command signal and convert it to coil current while drawing power from a 24 V DC supply. Hysteresis is held to 6 percent so position repeatability remains stable.
Installation uses a mounting interface that conforms to ISO 4401-07-06-0-94, and the pilot stage is built to size 6. The hydraulic medium may have a viscosity between 20 and 380 mm²/s and a temperature from −20 to +80 °C. System cleanliness must meet ISO 4406 class 20/18/15 for the main valve passage. Electrical connection is provided by a DIN EN 175201-804 plug that links the OBE to control wiring. The complete assembly weighs 13.6 kg. These characteristics support hydraulic automation that requires proportional flow and directional control.
