The Bosch Rexroth H-4WEH25D6X/6EG24N9ETS2K4/11B10D3 (R901083528) is a high-performance industrial hydraulic valve designed for reliable switching of oil flow direction, as indicated by its spool symbol D. This pilot-operated spool valve features internal pilot oil supply and return, with solenoid actuation that operates at a supply voltage of 24 VDC. It is suitable for subplate mounting and conforms to the connection diagrams of NFPA T..R D Size and CETOP D, as well as ISO standards. Equipped with a maximum pressure capacity and an electrical connector pole PE according to EN, this valve ensures robust performance in various applications. The number of ports and the type of connection are tailored for efficient fluid control within hydraulic systems. The valve can handle multiple types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. This model comes with NBR seals and a weight specification that contributes to its durability and ease of installation. Notably, it includes features such as spring or pressure centering, wet-pin DC or AC solenoids with optional electrical connections for individual or central connection setups. Additional options like manual override, switching time adjustment, preload valve in channel P of the main valve, stroke setting, and spool position monitoring are available to cater to specific application needs. The design includes return springs that maintain the main control spool in the central position without pilot pressure even in vertical positioning. However, it is important to note that internal leakage may increase over the life cycle due to the design principle. The valve's configuration allows for either internal or external pilot oil supply and return options depending on the specific type selected (HWEH...ET..., HWEH...E, etc.), providing versatility in hydraulic circuit integration. In summary, Bosch Rexroth's H-4WEH25D6X/6EG24N9ETS2K4/11B10D3 offers a comprehensive solution for sophisticated hydraulic control with customizable features suited for demanding environments where precise fluid management is essential.
