Bosch Rexroth 4WEH32HC6X/6EG24N9K4 electrohydraulic directional valve

4WEH32HC6X/6EG24N9K4, manufacturer material number R900916934, is a Bosch Rexroth pilot-operated directional spool valve with electrohydraulic actuation, factory size code 32, nominal size 32 and spool symbol C. The main spool controls flow direction; the pilot circuit moves the main spool. Its H return execution uses hydraulic return; a spring-return state must not be assumed.

Main-stage pressure, tank pressure and pilot pressure are independent. External pilot circuits require protection; internal pilot supply may require the specified pressure-reducing arrangement. Pressure–flow curves and minimum pilot-pressure requirements apply to the exact spool. Internal leakage is inherent to the spool design.

The mounting interface is a subplate pattern, not a threaded fluid fitting. Subplates and mounting screws are separately selected; the original pages show the applicable interfaces and installation requirements.
