The 4WRLE10W1-80SJ-3X/G24EK0/A1WX02M-756 is produced by Bosch Rexroth in the 4WRL Solenoid Valves series to meter hydraulic flow in automated machinery. The valve is designated nominal size 10, so it nests into NG10 cavities without adapter plates. Its ISO 4401-05-05-0-05 mounting interface lets users bolt the body directly to standardized subplates and manifold stacks. A peak flow capacity of 300 l/min supports medium-capacity circuits while maintaining acceptable pressure loss. The coil and electronics operate from a 24 VDC supply, and total power draw is limited to 40 VA to reduce panel loading. A 2.5 AT fuse on the incoming line provides over-current protection for the drive stage. Because the relative duty cycle is 100%, the unit can remain energized continuously without thermal derating. An IP65 enclosure rating keeps dust and low-pressure water jets away from the internal spool and electronics.
The integrated amplifier accepts a ±10 V command input so standard analog controllers can set spool position proportionally, and a matching ±10 V measuring output returns the actual position to the PLC for closed-loop monitoring. With an input impedance of 100 kΩ, the control card imposes minimal loading on upstream signal sources. Hydraulic limits allow 350 bar on ports p, a, and b for main flow paths, while the pilot port X is rated to 280 bar to protect the pilot circuit. Return ports T and y withstand 250 bar, securing safe tank lines in high-pressure systems. Stable operation requires at least 10 bar of pilot pressure, ensuring the pilot stage can shift the main spool reliably. The electronics tolerate up to 2.5 Vpp residual ripple on the power rail, preventing supply noise from disturbing valve accuracy.
