The Bosch Rexroth 4WEH22E7X/6EW110N9ETDK25L/10B10SO269 (R901342984) is a high-performance directional spool valve designed for electrohydraulic actuation, controlling the start, stop, and direction of fluid flow. This valve is engineered for subplate mounting with porting patterns conforming to ISO standards, available in 3- or 4-way versions. It features spring or pressure centering and offers options for spring end position or hydraulic end position. The unit includes wet-pin DC or AC solenoids which can be chosen based on application requirements, and these solenoids facilitate the movement of the main control spool by altering the pilot pressure in the spring chambers. The electrical connection can be either individual or central, adding to its installation versatility. Additionally, it has an optional manual override function that allows for manual operation without solenoid energization. The valve offers different types of actuation through either internal or external pilot control. For applications requiring precise control over pilot oil supply, a throttle insert can be used to limit flow in channel P of the pilot control valve. This particular model may also come with additional optional features such as switching time adjustment, a preload valve in channel P of the main valve, stroke setting, and spool position monitoring. It's important to note that any modification to the pilot oil supply should only be carried out by authorized specialists to ensure proper functioning and safety. The maximum operating parameters must always be observed as outlined in the data sheet provided by Bosch Rexroth. The design ensures reliable operation even with vertical valve positioning due to its return springs and pressure centering capabilities but acknowledges that internal leakage is inherent and may increase over its lifecycle.
