The Bosch Rexroth H-4WEH 25 E6X/6EW110N9ETK4=CSA (R978908413) is a high-performance electrohydraulic directional control valve designed for subplate mounting with a porting pattern that adheres to ISO standards. It is available in 3- or 4-way versions and can be actuated either internally or externally. This model features spring or pressure centering with options for spring end position or hydraulic end position, accommodating various application requirements. Equipped with wet-pin DC or AC solenoids, the H-4WEH 25 E6X/6EW110N9ETK4=CSA offers flexibility in electrical connections, allowing for individual or central connections. The valve is engineered to maintain the main control spool in a central position without pilot pressure due to its return springs, even when installed vertically. However, internal leakage is an inherent characteristic of this type of valve and may increase over its life cycle. The main control spool's zero position is secured by pressurization of both front faces and one centering bush that rests on the housing. Movement of the main control spool to the switching position occurs upon pressure relief of one front face, while the pilot oil supply and return are managed through different configurations depending on the type - external via channel X for pilot oil supply and external via channel Y into the tank for pilot oil return. Additionally, this model offers optional features such as manual override, switching time adjustment, preload valve in channel P of the main valve, as well as stroke setting and/or spool position monitoring. These additional capabilities provide users with enhanced control over their hydraulic systems' performance. The H-4WEH 25 E6X/6EW110N9ETK4=CSA is tailored for specialized applications requiring precise fluid control and is suitable for various electrohydraulic operations where reliability and adaptability are paramount.
