The Bosch Rexroth 4WREEM6E32J-2X/G24K34/B6V-687 (R900617253) is a high-performance, direct-operated proportional directional valve designed for precise control of flow direction and size in hydraulic systems. This valve is particularly suited for applications with stringent safety requirements, such as hydraulic press controls. It features a plate design with a symmetric spool overlap and incorporates an operating direction and spool central position monitoring function. The model also includes a step function to quickly compensate for spool overlap, ensuring responsive control. Equipped with proportional solenoids that have a central thread and detachable coil, the valve allows for straightforward operation. The integrated electronics facilitate solenoid control, while the inductive position transducer monitors the control spool's position. This feedback mechanism is critical for detecting any malfunctions and maintaining operational safety. The construction of the 4WREEM6E32J-2X/G24K34/B6V-687 includes a housing with a connection surface, a control spool balanced by compression springs, and solenoids with integrated electronics. When deenergized, the solenoids ensure the control spool remains in its central position due to the compression springs' action. Upon energization of one solenoid, the control spool moves proportionally to the electrical input signal. For safety-critical applications, this valve's design ensures that it can be part of a system meeting relevant standards like EN ISO 13849-1 or EN 61508. In case of power failure or absence of command signals, centering springs maintain the valve's spool in its central position to block or connect ports as required. The valve must be mounted correctly; it cannot be operated vertically with the spool position sensor upside down. Additionally, users are cautioned not to open the PG fitting or adjust the adjustment nut as this could damage the valve. Internal leakage is inherent due to design but should be considered over its lifecycle. Lastly, if installed under certain conditions where tank lines may run empty, installing a preload valve with approximately 5 bar preload pressure is recommended.
