The 4WRTE10V100L4X/6EG24TK31/A5M is manufactured by Bosch Rexroth as part of the 4WRTE Directional Control Valves series and is used to meter flow and pressure in hydraulic automation systems. It runs on a 24 V DC supply that remains functional between 18 V and 35 V, so moderate bus variation does not interrupt operation. A 100 kΩ input resistance places little load on motion controllers, while the command input accepts ±10 V and generates a matching ±10 V actual-value signal for closed-loop feedback. Continuous service is supported by a 100 percent duty cycle, and peak spool movement is handled by a 2.7 A impulse current even though steady draw is limited to 1.6 A. Residual ripple on the supply is restricted to 2.5 Vpp to protect the electronics, and an IP65 housing seals the assembly against dust and water projected during machine wash-down.
The hydraulic section is rated for 100 l/min so actuators receive predictable flow during normal operation, and line sizing can allow up to 170 l/min for brief demand peaks without losing control accuracy. A maximum working pressure of 350 bar lets the valve mount on high-pressure manifolds common in industrial presses and test rigs. External pilot oil supply ensures that control stages receive clean fluid, while internal pilot oil return channels drainage back into the main body to minimize hose routing. Together, these pilot paths keep the control chamber stable and reduce potential leak points. By combining the electrical limits defined above with the hydraulic capacities listed here, the valve maintains repeatable performance throughout continuous automated duty cycles.
