The Bosch Rexroth H-4WEH25D6X/6EG24N9SK4 (R900749584) is an electrohydraulic directional control valve designed for subplate mounting with a porting pattern according to ISO. This valve features a size D, symbol D spool and operates with a maximum pressure in high-performance industrial hydraulic systems. It is equipped with solenoid actuation, allowing reliable switching of oil flow direction, which is crucial for various hydraulic applications. The valve's spool operation can be spring or pressure centered, with the option of spring end position or hydraulic end position. It utilizes wet-pin DC solenoids which can be optionally supplied as AC. The electrical connection can be configured as an individual or central connection, providing flexibility for system integration. Additionally, the valve offers optional features such as manual override, switching time adjustment, a preload valve in channel P of the main valve, stroke setting, and/or spool position monitoring. This model has a maximum flow capacity and comes with NBR seals that are compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The valve also includes external pilot oil supply and return capabilities. For specific applications requiring adjustments to pilot oil supply or return parameters, the product includes instructions on integrating throttle inserts or pressure reducing valves to manage pressure peaks effectively. The design of the H-4WEH25D6X/6EG24N9SK4 ensures that it can maintain its central position due to return springs even when there is no pilot pressure or in vertical positioning scenarios. However, internal leakage may occur over time due to its design principle. This model offers numerous configurations for pilot oil supply and return – both internal and external – ensuring it meets various system requirements while maintaining operational integrity and performance standards in demanding environments.
