Product Overview
The Rexroth H-4WEH 25 J68/6EG24N9ETK4/B10D3 (Material No. R900932940) is a high-performance electro-hydraulic directional spool valve from the renowned 4WEH series, engineered for demanding industrial hydraulic systems requiring precise flow direction control under high pressure. This valve operates on a two-stage principle: a pilot-operated solenoid valve (size 6) controls the main stage spool (size 25), enabling reliable switching of large flow volumes with minimal electrical power. The “J68” spool configuration provides a specific flow path characteristic, while the “EG24” designation indicates a 24 V DC solenoid with emergency manual override. The “N9” signifies the standard manual override function, and the “ETK4” denotes the electrical connection type (terminal box with indicator light). The “B10D3” suffix specifies the pilot supply and drain configuration. This valve is a direct-fit replacement for OEM Rexroth components, ensuring seamless integration into existing hydraulic circuits.
