The Bosch Rexroth 4WRKE16R5-200L-3X/6EG24K31/A1D3M-622 (R900708337) is a high-performance pilot-operated 2-stage proportional directional valve with electrical position feedback and integrated electronics (OBE). It is designed for subplate mounting with a porting pattern according to ISO standards. This valve features a single-stage pilot control valve that optimizes the control edge geometry specifically for use as a pilot for WRKE type valves. The proportional solenoids are wet-pin DC solenoids, ensuring pressure tightness and reliable operation with detachable coils, which translate electric current into mechanical force proportionally. The main stage of the valve is position-controlled, meaning it maintains the control spool position independently of flow forces, even in high-flow situations. The main control spool is spring-centered and connected to control electronics through an inductive position transducer, allowing precise feedback and adjustment of the spool's position to match command values. The integrated control electronics are finely tuned to minimize device variation in series production. This model comes equipped with features such as zero point adjustment, which is factory-set but can be fine-tuned onsite by qualified experts. It also includes access to integrated control electronics via a removable plug screw on the front side of the cover housing. The valve ensures consistent performance across its operational range and requires that tank lines maintain a preload pressure of approximately 5 bar to avoid running empty. The Bosch Rexroth 4WRKE16R5-200L-3X/6EG24K31/A1D3M-622 is particularly suited for applications requiring precise control over flow direction and size, utilizing proportional solenoid operation for responsiveness and accuracy. It should be noted that any adjustments or changes to the zero point should only be conducted by trained specialists to prevent potential damage to the system.
