Bosch Rexroth H-4WEH WE6 Hydraulic Directional Control Solenoid Spool Valve

Bosch Rexroth H-4WEH WE6 is a direct-operated, 4-way hydraulic directional spool valve designed for compact, high‑reliability control in hydraulic circuits. This H‑4WEH WE6 configuration represents a size six valve in Rexroth’s WEH family, typically configured as a 4/3 directional valve with pressure centering of the main control spool, enabling a defined neutral position when the solenoid is de-energized. The solenoid coil is powered from 110–120 V AC, making it compatible with standard industrial power supplies for automated equipment. Rated for hydraulic system pressures up to about 350 bar, the WE6 valve supports robust flow-direction control in demanding applications where space is limited. As an electro-hydraulic directional control valve, it combines a pilot control valve with a main spool to deliver precise, repeatable switching of flow paths between pressure port P, tank T, and the work ports A and B, enabling reliable actuation of cylinders or hydraulic motors. Typical applications include machine tools, presses, clamping systems, and automated production lines where compact packaging and dependable steering of hydraulic flow are essential. Leveraging Rexroth’s WE interface standard, the H-4WEH WE6 integrates with common Rexroth pilot-control configurations, offering predictable response characteristics and compatibility with established control architectures in industrial hydraulics.
