The Bosch Rexroth DBAW40BH2N1X/315S6EG24N9K4R12 (R900976490) is a high-performance pump safety block designed for direct mounting onto the SAE pressure port of hydraulic pumps. This pilot-operated pressure relief valve is an integral part of ensuring system safety by limiting the operating pressure within hydraulic systems. The unit comprises a valve block, a main spool insert, and a pilot control valve that facilitates precise pressure adjustments. It features ports for hydraulic fluid input and output, with the main spool insert controlling the connection to the tank line when open. This model also includes functionality to switch between pressure limiting and depressurized circulation through its built-on directional valve, allowing for zero-pressure startup of the pump, which can be critical in various operational scenarios. Moreover, this pump safety block is equipped with switching shock damping capabilities when used with corresponding sandwich plates (types DBAWSE...R and DBAWSSM...B). This feature helps delay the opening from B to B or P to P, mitigating pressure peaks and reducing acoustic decompression shocks in the return line. The degree of damping decompression shock is adjustable via nozzle size, with a standard nozzle installed as per ordering codes. Users can select from multiple adjustment types for setting the operating pressure, including options like a rotary knob or lockable rotary knob with scale. Additionally, there are optional features such as solenoid-actuated unloading via the built-on directional valve and an integrated check valve. Overall, this Bosch Rexroth pump safety block offers robust performance and versatile options to ensure reliable operation in various hydraulic applications where quick pressure buildup and safe operation are essential.
