The Bosch Rexroth 4WRTE10E100L-4X/6EG24ETK31/A5V (R901513074) is a sophisticated pilot-operated directional control valve designed with integrated electronics and optional spool position monitoring for advanced hydraulic control applications. This valve features an electrical position feedback system, ensuring precise control and feedback for various operational states. It is structured into several main assemblies, including the housing with main stage control spool, integrated electronics with optional protection membrane, and pilot control valve with inductive position transducers. The functionality of the 4WRTE10E100L-4X/6EG24ETK31/A5V allows for controlled movement of the main stage spool via the pilot control valve, which is regulated by proportional solenoids. The solenoids' force adjustment leads to precise command value connection within the integrated electronics. The valve also provides options for internal or external pilot oil supply and return, accommodating diverse installation requirements. Spool position monitoring is a significant feature of this model; it employs an inductive switch to detect spool positions and relay them through switching outputs for superior control monitoring functions. This capability makes it suitable for safety-related applications that require high reliability, such as those conforming to EN standards for stop category 0 start inhibitors. The electronics protection membrane option is recommended for environments with high humidity or temperature fluctuations, preventing condensation within the electronic housing. In case of supply voltage failure or pressure supply issues, the valve automatically maintains pressure equilibrium in the control chambers or centers the main stage spool via a centering spring. Overall, this Bosch Rexroth directional control valve stands out due to its automatic pressure compensation feature in the control chambers by the pilot control valve, reliable design suitable for various motion controls like position, velocity, and pressure adjustments while offering high response sensitivity with minimal hysteresis.
