The Bosch Rexroth DBW 20 B2-5X/200US6EW110RN9DK23LR10/12 (R978005734) is a sophisticated pressure relief valve designed for advanced hydraulic systems requiring precise pressure limitation and solenoid-actuated unloading. This pilot-operated valve integrates a main spool insert and a pilot control valve with an adjustable pressure element, along with an integrated directional spool valve. Its primary function mirrors that of the DB valve type; however, it uniquely achieves the unloading of the main spool through the control of the attached directional spool valve. Featuring switching shock damping in its sandwich plate design, this model ensures that the opening from B to B is delayed, effectively mitigating pressure peaks and reducing acoustic decompression shocks in return lines. This is accomplished by installing it between the pilot control valve and the directional valve. The extent of damping is influenced by nozzle size, with a specific recommendation for ordering code R to optimize performance. Designed for subplate mounting, it supports various porting patterns compliant with ISO standards NG6, NG10, and NG16. It can also be utilized as a screw-in cartridge valve for threaded connections. Users have multiple adjustment options for setting pressure levels including rotary knobs (with or without scales), sleeves with hexagon and protective cap, or lockable rotary knobs with scales. The DBW 20 B2-5X/200US6EW110RN9DK23LR10/12 can handle maximum operating pressures up to a certain bar level and offers a maximum flow rate measured in liters per minute. Its high-power solenoid enables solenoid-operated unloading via either built-on directional spool valves or directional poppet valves. Additionally, optional switching shock damping enhances its operational capabilities. This product is suitable for various applications where precise pressure control and reliability are paramount.
