The Bosch Rexroth H-4WEH25D6X/6EG24N9EK4/B10D3VSO388 (R901353095) is a highly sophisticated electrohydraulic directional control valve designed for subplate mounting with a porting pattern according to ISO standards. This advanced valve is engineered for precise control in hydraulic systems, offering configurations such as 3-way or 4-way versions with spring or pressure centering and spring end position or hydraulic end position. Featuring wet-pin DC or AC solenoids, the valve can be tailored to meet specific operational requirements with options for individual or central electrical connections. The versatility of the H-4WEH25D6X/6EG24N9EK4/B10D3VSO388 is further enhanced through additional optional features such as manual override, switching time adjustment, preload valve in channel P of the main valve, stroke setting, and spool position monitoring. The design incorporates return springs that maintain the main control spool in a central position without pilot pressure, ensuring stability even in vertical orientations. However, it's important to note that internal leakage is an inherent characteristic that may increase over the product's lifecycle. The main control spool is pressure-centered and can be shifted from its zero position by relieving pressure from one side while the other side displaces pilot oil externally via the pilot control valve. For pilot oil supply and return, this model offers flexibility with external supply via channel X from a separate pressure source and external return via channel Y into the tank. It also allows for internal configurations where the supply comes from channel P of the main valve and returns internally via channel T into the tank. The use of a throttle insert is necessary to limit pilot oil supply when required, ensuring controlled operation. This insert is placed in channel P of the pilot control valve. Modifications to the pilot oil supply should only be performed by authorized personnel or at the factory to maintain system integrity and performance.
