The Bosch Rexroth 4WRKE16W8-200L-3X/6EG24EK31/A5D3WC15M (R901105145) is a state-of-the-art pilot-operated 2-stage proportional directional valve designed for precise control of flow direction and magnitude in hydraulic systems. It features an electrical position feedback mechanism for the main control spool and integrated electronics (OBE). The valve's pilot control is a single-stage proportional directional valve that optimizes the control edge geometry, specifically tailored for use with WRKE-type valves. This model boasts wet-pin DC solenoids with detachable coils that are pressure-tight, converting electric current proportionally into mechanical force to maintain consistent solenoid force throughout the entire control stroke. The main stage of the valve is position-controlled, ensuring that the spool's position remains constant regardless of flow forces, even at higher flows. This attribute makes it ideal for applications requiring precise movement and positioning. The 4WRKE16W8-200L-3X/6EG24EK31/A5D3WC15M is designed for subplate mounting and conforms to ISO porting patterns. It comes equipped with spring-centered main control spools that are held in a neutral position by centering springs when there's no input signal. The inductive position transducer linked to the main control spool ensures accurate feedback to the integrated electronics, which adjust the proportional solenoid's current based on command values. Valve adjustments are meticulously set at the factory, including zero-point calibration of the main stage within a specific range via a potentiometer in the control electronics. However, any further adjustments or replacements of components such as pilot control valves or electronics should be carried out exclusively by trained specialists due to potential system damage risks. Overall, this Bosch Rexroth proportional directional valve offers high precision and reliability for hydraulic system applications where meticulous flow control is paramount.
