The Bosch Rexroth 4WEH 22 J7X/6EG24N9ESK4 (R900930375) is a high-performance directional spool valve with electrohydraulic actuation designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This particular model features wet-pin DC or AC solenoids for operation and offers multiple configurations including spring or pressure centering, and spring end position or hydraulic end position. The valve is engineered for subplate mounting and follows the porting pattern according to ISO standards. It is suitable for both 3-way and 4-way versions, ensuring versatility for various circuit configurations. The unit includes optional manual override functionality, allowing operators to manually control the valve in the absence of electrical power. Additionally, the 4WEH 22 J7X/6EG24N9ESK4 valve provides options for switching time adjustment to cater to specific application requirements. For systems necessitating precise pressure control within the main valve circuit, a preload valve can be included in channel P of the main valve. Stroke setting and/or spool position monitoring can also be integrated into this model, contributing to enhanced control accuracy and system feedback. This Bosch Rexroth directional valve ensures reliable performance even in demanding applications, thanks to its robust design which includes return springs that maintain the main control spool in a central position without pilot pressure. It is important to note that internal leakage may occur due to its design principle; however, this is considered normal behavior over its lifecycle. For hydraulic systems requiring regulated pilot oil supply and return flow rates, throttle inserts are available and can be fitted into channel P of the pilot control valve as necessary. Modifications regarding pilot oil supply should only be carried out by authorized specialists or at the factory to ensure proper function and adherence to maximum operating parameters as specified in technical data sheets.
