The Bosch Rexroth 4WRKE25E350L-3X/6EG24TK31/A1D3M-497 (R900703268) is a sophisticated pilot-operated stage proportional directional valve designed to manage flow direction and magnitude with high precision. This valve features electrical position feedback of the main control spool and integrated electronics OBE, ensuring accurate performance and ease of use. It is engineered for subplate mounting with a porting pattern according to ISO standards. The unit's key component, the pilot control valve, is a single-stage proportional directional valve that utilizes optimized control edge geometry specifically tailored for use with proportional directional valves of type WRKE. The valve's proportional solenoids are pressure-tight, wet-pin DC solenoids with detachable coils, which reliably convert electric current into mechanical force. This force remains constant across the entire control stroke, allowing for precise manipulation of the main stage. The main stage of the 4WRKE25E350L-3X/6EG24TK31/A1D3M-497 boasts position control that maintains the position of the control spool independently from flow forces even at higher flows. A spring-centered main control spool ensures stability in a neutral state while an inductive position transducer communicates spool displacement to the integrated control electronics for real-time adjustments. This model includes features such as zero point adjustment and access to integrated control electronics through a front cover housing plug screw. Adjustments are factory-set but can be fine-tuned by trained experts if necessary, ensuring optimal performance tailored to specific system needs. Please note that any changes or adjustments must be performed by qualified personnel to prevent potential damage to the system. Additionally, installation conditions require attention as tank lines must not run empty; a preload valve with approximately 5 bar preload pressure may be needed depending on setup specifics.
