The Bosch Rexroth 4WRKE16R3-125L-3X/6EG24ETK31F1D3M (R901165622) is a high-performance, pilot-operated stage proportional directional valve designed for precise control of flow direction and size in hydraulic systems. This valve is equipped with electrical position feedback and integrated electronics (OBE) to ensure accurate and responsive operation. The 4WRKE16R3-125L-3X/6EG24ETK31F1D3M is specifically optimized for use as a pilot control valve for proportional directional valves type WRKE, featuring an optimized control edge geometry. The valve's construction includes a robust housing, pressure-tight wet-pin DC solenoids with detachable coils that convert electric current into mechanical force proportionally, a valve control spool, and springs to maintain consistent solenoid force throughout the entire control stroke. In its default state, the actuators are connected to the tank, but when activated by an electric current, the spool moves to change the connection from the tank to the pressure chamber, allowing flow from P to the main stage's control chamber. Designed for subplate mounting with porting patterns according to ISO standards, this model ensures stable performance even with larger flows due to its position-controlled main stage. The main control spool remains centered by a spring in a neutral state and utilizes an inductive position transducer for feedback that interacts with integrated electronics to match command values with actual positions. The 4WRKE16R3-125L-3X/6EG24ETK31F1D3M also features a pressure reducing valve and allows for zero-point adjustment within a specific range via potentiometer. Adjustments and maintenance should only be performed by trained specialists due to the precision of the components and potential system damage if improperly handled. This Bosch Rexroth valve stands out for its modular second stage setup and commitment to maintaining low deviation across devices through careful calibration of both valve and electronics.
