The Bosch Rexroth DBAWR40AH2N1X/315S6SMG24N9K4B12 (R900937540) is a sophisticated pump safety block designed for direct mounting onto the SAE pressure port of pumps. This pilot-operated pressure relief valve is engineered to limit operating pressures, ensuring optimal performance and safety in hydraulic systems. The unit comprises a valve block, a main spool insert, and a pilot control valve with various adjustment types for precise pressure regulation. Its housing features an input port P and an output port P, with the main spool insert situated within the throughbore between these ports to facilitate connection to the tank line port T when open. Furthermore, this model boasts a built-in directional valve that allows for switching between pressure limiting functions and depressurized circulation, enabling a zero-pressure startup of the pump. The DBAWR40AH2N1X/315S6SMG24N9K4B12 also includes switching shock damping capabilities with its sandwich plate design, which delays the opening from B to B or P to P. This feature helps mitigate pressure peaks and reduce acoustic decompression shocks in return lines. The degree of damping decompression shock can be adjusted according to nozzle size; by default, it comes with a specific nozzle size denoted in its ordering code. Users have multiple options for adjusting pressure settings, including rotary knobs and lockable rotary knobs with scales or sleeves with hexagons and protective caps. Additional optional features include solenoid-actuated unloading via the built-in directional valve, an integrated check valve for preventing reverse flow, and switching shock damping for enhanced system protection. This pump safety block is designed for quick pressure buildup with adjustable pressure ratings to meet various application requirements efficiently.
