The Bosch Rexroth DBW 20 A5-5X/315XYM6EG24N9K4 (R901076448) is a sophisticated pressure relief valve designed for advanced hydraulic applications. This pilot-operated valve is engineered to limit and control the unloading of operating pressure in a precise manner. The core components include a main valve with a spool insert and a pilot control valve that comes with an adjustable pressure element, as well as an integrated directional spool valve. This particular model offers enhanced functionality similar to the DB valve series, with the added benefit of solenoid-actuated unloading facilitated by the mounted directional spool valve. The DBW 20 A5-5X/315XYM6EG24N9K4 features switching shock damping capabilities, thanks to its sandwich plate design. This function delays the opening from port B to B, effectively mitigating pressure peaks and reducing acoustic decompression shocks in the return line. This protective measure is achieved by installing it between the pilot control valve and the directional valve. Furthermore, users can customize the degree of decompression shock damping by selecting an appropriate nozzle size; for instance, a nozzle with an ordering code R is recommended for general purposes. The unit is versatile in its mounting options, supporting subplate mounting with porting patterns compliant with ISO standards NG6, NG10, and NG16, as well as being available for threaded connections or as a screw-in cartridge valve. The adjustment types provided for setting the pressure are user-friendly and come in various forms including rotary knobs—both standard and lockable versions—with or without scales, and sleeves with hexagons protected by caps. Its high-power solenoid ensures reliable operation when unloading via built-on directional spool valves or poppet valves. Additionally, optional switching shock damping further enhances system protection and performance stability across diverse hydraulic applications.
