The 4WRTE10W6-50P-4X/6EG24ETK31/A5V-280 valve is produced by Bosch Rexroth for the 4WRTE Directional Control Valves series. It directs hydraulic flow in automation circuits where proportional control is needed. The valve uses nominal size NG10 passages to match medium-capacity manifolds, and it delivers a rated flow of 50 l/min for consistent actuator speed. Its linear Fine Control P flow characteristic supports precise positioning tasks. The assembly withstands operating pressures up to 350 bar, so it suits high-pressure systems. Control accuracy is supported by hysteresis not exceeding 0.1 % and response sensitivity of up to 0.05 %, limiting deviation during small command changes. Fluid cleanliness must meet ISO 4406 class 18/16/13 to protect the spool and electronics from contamination. For installation, the body follows mounting pattern ISO 4401-05-05-0-05, allowing direct placement on standard subplates.
The electronics are supplied with a nominal 24 VDC, while maximum current draw is 1.6 A, so power wiring can be sized accordingly. Peak electrical demand reaches 72 VA, indicating overall energy requirements for the integrated amplifier. The input stage presents 100 kΩ resistance, which places minimal load on the command signal source, and a high-level enable input of 11 VDC is required to activate the valve. Circuit protection is achieved with a 4 A time-lag fuse that accommodates inrush without nuisance trips. The enclosure meets IP65, guarding against dust ingress and water jets in typical machine environments. The unit weighs 8.7 kg, which should be considered for manifold support and service handling.
