The Bosch Rexroth H-4WEH25E6X/6EG24NK4 (R900958090) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction in hydraulic systems. It features a spool valve with pilot operation and an E symbol spool, which ensures precise control. This model is equipped with external pilot oil supply and return capabilities, enhancing its functionality and flexibility within various applications. The valve operates at a maximum pressure, with electrical actuation provided by solenoids that are energized by a 24VDC supply voltage. The H-4WEH25E6X/6EG24NK4 valve offers multiple switching positions and has a robust construction that includes NBR seals suitable for hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. Its subplate mounting design adheres to NFPA T3.5.1 R2 D03 and ISO 4401 standards, ensuring compatibility with industry-standard configurations. Additionally, the unit's weight is optimized for ease of installation without compromising durability. This model employs an innovative pressure centering mechanism for the main control spool, utilizing return springs to maintain the spool in the central position when there's no pilot pressure or in vertical valve positioning scenarios. However, it's important to note that internal leakage can be inherent to these valves over their lifecycle due to their design principle. Designed primarily for electrohydraulic applications requiring precise actuation and control, the Bosch Rexroth H-4WEH25E6X/6EG24NK4 provides versatility through optional features such as manual override capabilities, switching time adjustments, preload valves in channel P of the main valve, stroke setting adjustments, and spool position monitoring. Its ability to cater to both spring or pressure centering configurations makes it suitable for a wide range of operational demands in sophisticated hydraulic systems.
