The Bosch Rexroth DBEM20-7X/100YG24K4M (R901353029) is a sophisticated, pilot-operated pressure relief valve designed to regulate operating pressure within hydraulic systems. This valve excels in providing stepless control of pressure settings, responding to electrical command values for precise operation. The DBEM20-7X/100YG24K4M features a durable housing that contains the main spool insert, a sandwich plate valve for maximum pressure limitation, and a proportional pilot control valve. The functionality of this model is centered around its ability to manage the pressure exerted on the main spool through channel P. The design incorporates control lines with nozzles and a connecting bore that directs pressure to the proportional pilot control valve's poppet. This system balances hydraulic force against the force generated by the proportional solenoid, ensuring reliable operation and response to varying pressures. Inbuilt safety mechanisms include a spring-loaded pressure relief valve preset according to specific pressure ratings. This ensures protection against excessive pressures by opening up when the set maximum admissible pressure is surpassed, allowing pilot oil to flow back into the tank and reducing the main spool's pressure. For customization and adaptability, an adjustment element is included for altering preset pressures when necessary. The DBEM20-7X/100YG24K4M also requires external piping to the tank for port Y and suggests that this connection be depressurized. Additionally, port X offers options for unloading or further limiting maximum pressure. This model is designed for subplate mounting with threaded connections conforming to ISO standards, ensuring compatibility with various setups. It combines both valve mechanics and control electronics in one package; however, external control electronics are required and must be ordered separately. With its precise control capabilities and robust safety features, this Bosch Rexroth valve stands out as an essential component for advanced hydraulic systems requiring reliable pressure relief functions.
