The 4WRTE10V50P-4X/6EG24TK31/A5M valve is produced by Bosch Rexroth within the 4WRTE Directional Control Valves series and regulates hydraulic flow in automated systems. It operates on a nominal 24 VDC supply and draws up to 1.6 A, so a 4 A time-lag fuse is specified for circuit protection. The solenoid’s peak demand is 72 VA, and incoming power must maintain residual ripple below 2.5 Vpp to keep the electronics stable. A rated flow of 50 l/min is achieved at a 5 bar pressure drop across the control edge. Pilot oil is introduced externally and returned internally, reducing port complexity on the main manifold. Electrical hookup is through a plug that conforms to DIN EN 175201-804 type K31, and spool positioning repeatability is supported by a maximum hysteresis of 0.1 %.
The hydraulic section withstands operating pressures up to 350 bar, while the external T return line can handle 315 bar, enabling use in high-pressure circuits. Coil insulation endures temperatures reaching 150 °C, and the housing carries an IP65 rating to resist dust ingress and water jets when the connector is secured. NBR seals are fitted for compatibility with standard mineral hydraulic fluids, and the fluid cleanliness must meet ISO 4406 class 18/16/13 to protect the metering edges from abrasive wear. These limits together secure consistent performance and long service life under demanding duty cycles.
