The Bosch Rexroth L-DB40F2-3X/16 (R900353789) is a high-performance pressure relief valve, specifically engineered for applications requiring efficient control over high flow systems with low preload pressures. This particular model is part of the Type LDB series, which features a robust design including a pipeline installation housing, a main spool guide to accommodate the pilot control valve, and a main spool that ensures precise operation. The L-DB40F2-3X/16 operates by applying pressure to channel P, which acts on the main spool while simultaneously being directed to the pilot control valve through nozzles. Should the pressure in channel P surpass the preset value at the pilot control valve, it triggers the valve to open and allows the pilot oil to discharge directly into channel Y. Consequently, this action causes the main spool to ascend against springs, thereby connecting channel P to channel T whenever the pressure goes beyond what is set at the pilot control valve. This model also offers an alternative version U configuration where an external spring solely retains the main spool in its closed position. When there is no load on the control channel, this version facilitates achieving lower circulation pressure. Moreover, similar in function to Type LDB is Type LDBF; however, it distinguishes itself by being designed as a cartridge valve without pipeline housing. It allows for flange connections and adheres to DIN EN ISO standards for pressure ratings. The adjustment type for setting pressure levels in this model utilizes a sleeve with hexagon and protective cap for secure and precise calibration. In summary, Bosch Rexroth's L-DB40F2-3X/16 is tailored for those needing reliable and effective management of high-flow systems with low preload pressures while ensuring ease of maintenance and adjustment through its well-thought-out design features.
