The Bosch Rexroth 4WEH 22 G7X/6EG24N9ETK4/P45 (R900930144) is a high-performance directional spool valve designed for subplate mounting with electrohydraulic actuation, suitable for controlling the start, stop, and direction of fluid flow in hydraulic systems. This model features wet-pin DC or AC solenoids and offers options for individual or central electrical connections. It adheres to ISO porting patterns and is available in 3-way or 4-way versions.
The valve's main control spool can be spring-centered or pressure-centered, with the capability of spring end position or hydraulic end position retention. The spring chambers ensure the spool remains in a central position when not pressurized, even in vertical installations. The pilot control valve regulates pilot oil supply which can be internal from channel P of the main valve (in ET and E versions) or external via channel X from a separate pressure supply. Pilot oil return can be directed externally into the tank through channel Y or internally through channel T.
Additional features include manual override options, switching time adjustment capabilities, preload valves in channel P of the main valve, as well as stroke setting and/or spool position monitoring for precise control. The throttle insert is necessary to limit pilot oil supply if required, ensuring safe operation within specified parameters.
Users benefit from the robust design which includes leakages inherent to such valves but may increase over their lifecycle. It's important to note that any modifications should only be performed by authorized specialists to maintain operational integrity and safety. This model is ideal for applications requiring reliable directional control with customizable actuation methods and connection preferences.
