The Bosch Rexroth H-4WEH 22 E7X/6EG24N9ETS2K4 (R900930430) is a highly sophisticated electrohydraulic directional control valve designed for subplate mounting with a porting pattern that conforms to ISO standards. This model features a 4-way configuration and offers users the flexibility of spring or pressure centering, with options for spring end position or hydraulic end position. The valve is engineered to maintain the main control spool in a central position without pilot pressure due to its return springs, even when mounted vertically. This particular valve exhibits an internal leakage by design, which may increase throughout its lifecycle. It includes a pressure centering mechanism where the main control spool is held in zero position by pressurization on both front faces, and movement to the switching position is achieved by pressure relief of one front face. The H-4WEH 22 E7X/6EG24N9ETS2K4 supports various types of actuation including internal or external pilot control and can be fitted with either wet-pin DC or AC solenoids, depending on user requirements. Electrical connections can be made via individual or central connections. Additionally, this model provides options for manual override, switching time adjustment, preload valve in channel P of the main valve, as well as stroke setting and/or spool position monitoring for enhanced operational control. The pilot oil supply and return can be configured externally or internally depending on the specific type designation (ET... or E...), ensuring versatility in application across different hydraulic systems. It also requires the use of a throttle insert if there's a need to limit pilot oil supply in channel P of the pilot control valve. This Bosch Rexroth valve is suitable for applications requiring precise control over fluid direction within hydraulic systems, providing reliability and performance backed by Bosch Rexroth's expertise in fluid power engineering.
