The 4WRTE32W6-600L-4X/6EG24K31/A5M valve is produced by Bosch Rexroth within the 4WRTE Directional Control Valves series. It directs hydraulic flow in automation circuits. The valve accepts a ±10 V command and feedback signal to enable proportional spool positioning by external controllers. A nominal supply of 24 V DC energizes the integrated electronics while limiting current draw to 1.6 A; this confines power demand to 72 VA so cabinet supplies are not overloaded. Connection to the machine harness is made through a DIN EN 175201-804 (K31) plug, simplifying wiring. The housing carries an IP65 rating which protects internal components against dust and water jets encountered in industrial environments. NBR seals maintain compatibility with common mineral oils and provide reliable leakage control. The unit follows the ISO 4401-10-09-0-05 mounting pattern and is classified as size NG32, allowing direct replacement on standardized sub-plates. A mass of 31.5 kg must be considered when selecting manifold supports and handling equipment.
Flow through the valve follows a linear characteristic so actuator speed responds proportionally to input voltage changes. At a differential pressure of 5 bar, the rated flow reaches 600 l/min, enabling the control of large cylinders or hydraulic motors. The main ports P, A, and B tolerate continuous operating pressures up to 350 bar, while the external tank port can return fluid at pressures as high as 250 bar; these limits define the safe working envelope of the system. External pilot supply and return lines isolate the control stage from main line pressure, and the pilot circuit may be fed with pressures up to 315 bar to drive the spool reliably under load. These hydraulic limits, combined with the previously noted electrical and mechanical parameters, support precise high-flow direction control in press, molding, or heavy equipment applications.
