The Bosch Rexroth SYDZ 0001-1X/250V071M (R900539575) is a specialized pump preload valve designed to manage the flow control of variable displacement pumps, particularly the AVSO series with SYDFE adjustment. This component is engineered to be effective within a specific pressure range, ensuring that pressure preloading is only active up to a certain bar level. When the operating pressure at port P surpasses this threshold, the preload valve fully opens. To safeguard against excessive pressure, it incorporates a non-adjustable, factory-set pressure relief valve. An additional feature of this model includes an integrated check valve which facilitates pressure control below the specified bar limit. However, it's critical to note that the pressure limiting function serves as a safety measure and is not intended for continuous operation. Proper system bleeding is required upon commissioning to ensure optimal performance. The SYDZ 0001-1X/250V071M pump preload valve boasts an integrated design combining both preload and maximum pressure limitation functions. The limitation settings are predetermined according to the ordering code provided in the type key and are not user-adjustable post-manufacture. This unit is directly attachable at the SAE pressure connection of AVSO variable displacement pumps as detailed in documentation RE and RE. With its specific size and maximum operating pressure capacity of bar, this Bosch Rexroth pump preload valve is crucial for applications requiring controlled pump operations at lower pressures when only internal pilot fluid is available for adjustment. Its robust construction ensures reliability and safety in system operations where precise hydraulic control is essential.
