The Bosch Rexroth H-4WEH32X80-6X/6EG24N9ETK4/11B25D3 (R900705003) is a highly sophisticated directional control valve designed for electrohydraulic applications. This valve is engineered for subplate mounting and adheres to the ISO porting pattern. It can function as a 3-way or 4-way valve and features spring or pressure centering, with options for spring end position or hydraulic end position. The H-4WEH series valves are equipped with wet-pin DC or AC solenoids, which can be connected individually or centrally depending on the system's requirements. This model includes a throttle insert which is necessary when limiting the pilot oil supply in channel P of the pilot control valve. The main control spool of the valve is maintained in a zero position by pressurization of its two front faces, ensuring reliable operation. Pressure relief of one front face allows for switching positions, while the opposite face displaces returning pilot oil externally via the pilot control valve. For this specific model, the return springs do not serve as a return function but hold the main control spool in a central position when depressurized and installed horizontally. The pilot oil supply can be implemented either internally from channel P of the main valve or externally from a separate pressure supply via channel X. Similarly, pilot oil return can be managed internally via channel T into the tank or externally via channel Y. The valve offers optional features such as manual override, switching time adjustment, preload valve in channel P of the main valve, stroke setting, and spool position monitoring to enhance its functionality and adaptability to various electrohydraulic systems. This product is an essential component for those seeking precise control in hydraulic systems requiring high levels of reliability and customization.
