The Bosch Rexroth DBWC.3-5X/200 (R901117936) is a sophisticated pilot-operated pressure relief valve designed to manage and solenoid-actuated unloading of operating pressure in hydraulic systems. This valve combines a main valve with a main spool insert and a pilot control valve that includes a pressure adjustment element along with an integrated directional spool valve, ensuring precise control and relief functions. The DBWC.3-5X/200 model provides the same essential functions as the DB type valves, but distinguishes itself by unloading the main spool via an auxiliary directional spool valve. This particular model features switching shock damping, which is incorporated into its sandwich plate design. This function delays the opening from port B to B, effectively minimizing pressure peaks and reducing acoustic decompression shocks in the return line—a critical feature for maintaining system stability and longevity. The degree of damping can be tailored by selecting the appropriate nozzle size; a nozzle ordering code R is typically recommended. Designed for versatility, the DBWC.3-5X/200 can be mounted using subplate mounting with porting patterns conforming to ISO standards NG6, NG10, and NG16 or utilized as a screw-in cartridge valve for threaded connections. The pressure adjustment can be customized with various types of adjustment elements including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale based on user preference. The unit's high-power solenoid enables solenoid-operated unloading through either built-on directional spool valves or directional poppet valves. With such features, this Bosch Rexroth pressure relief valve stands out as an essential component for hydraulic systems requiring precise pressure control and reliability in operation.
