Rexroth 4WE6
Bosch Rexroth, a pioneer in drive and control technologies, strengthens its portfolio of hydraulic components with the 4WE6 series directional control valves—a compact, high-reliability solution engineered for precise flow and pressure management in industrial and mobile hydraulic applications.
Designed as a core component for directional control in open-circuit systems, the 4WE6 series features a spool valve structure with nominal flow rates up to 60 L/min and a maximum operating pressure of 315 bar, making it ideal for medium-duty hydraulic setups across manufacturing, construction, and automation sectors. Its modular design allows seamless integration with a wide range of actuation options, including solenoid, hydraulic, and manual actuation, to match diverse operational needs.
A key advantage of the 4WE6 valves is their exceptional switching precision and repeatability. The optimized spool geometry minimizes internal leakage and pressure drops, ensuring consistent performance even under fluctuating load conditions. For automated systems, the solenoid-actuated variants deliver fast response times (≤ 10 ms) and low power consumption, supporting energy-efficient machine operation. Additionally, the valves are equipped with robust sealing systems (FKM as standard) that resist harsh fluids and temperatures ranging from -20°C to +80°C, extending service life in demanding environments.
Versatility is another standout feature of the 4WE6 series. With multiple spool types (e.g., 4/2, 4/3, 3/2 way) and optional auxiliary functions like pressure relief and check valves, the valves can be customized for tasks such as cylinder positioning, motor speed control, and load holding. They comply with ISO 4401 and DIN 24340 standards, ensuring interchangeability with existing hydraulic systems and reducing retrofitting costs for manufacturers.
In practical applications, the 4WE6 series excels in scenarios requiring compact installation space—such as in robotic arms, packaging machinery, and small construction equipment. Its lightweight aluminum housing reduces overall system weight, while the integrated connection ports simplify piping and maintenance.
“ The 4WE6 directional control valve is a testament to Rexroth’s commitment to balancing performance, compactness, and cost-effectiveness,” stated a Bosch Rexroth product manager. “ It’s a go-to choice for engineers seeking reliable, flexible control solutions that adapt to the evolving demands of modern hydraulic systems.”
Available globally with comprehensive technical support and spare parts services, the Bosch Rexroth 4WE6 series continues to set a benchmark for directional control valves in the industrial hydraulics market.
