The Bosch Rexroth H-4WEH 25 E6X/6EW220NES2DAL/B10D3 (R978909575) is a high-performance electrohydraulic directional control valve designed for subplate mounting with porting patterns conforming to ISO standards. This model is a 4/3 or 4/2 way version, equipped with features such as spring or pressure centering and spring end position or hydraulic end position. It is suitable for applications where precise control of the hydraulic flow is required. The valve boasts wet-pin DC or AC solenoids, which can be selected based on the electrical requirements of the system, and offers the flexibility of either individual or central electrical connections. For enhanced operational versatility, this model comes with optional features like manual override, switching time adjustment, a preload valve in channel P of the main valve, and options for stroke setting and/or spool position monitoring. It includes a throttle insert necessary when limiting the pilot oil supply in channel P of the pilot control valve is required. The pilot oil supply can be configured either internally from channel P of the main valve or externally via channel X from a separate pressure supply. Similarly, the pilot oil return can be directed externally through channel Y into the tank or internally via channel T. The H-4WEH 25 E6X/6EW220NES2DAL/B10D3 has been engineered with return springs that maintain the main control spool in a central position without pilot pressure even when mounted vertically. However, it should be noted that internal leakage is inherent to these valves and may increase over their lifecycle due to their design principle. In summary, this Bosch Rexroth directional control valve provides robust performance and flexible configuration options for complex hydraulic systems requiring reliable actuation and flow control.
