The Bosch Rexroth SYDZ 0001-1X/250V028M (R900537402) is a pump preload valve designed to ensure efficient pressure preloading within a specific pressure range. This product features an integrated pressure relief valve that is permanently set at the factory, as per the ordering code, to regulate the maximum pressure. Additionally, it includes an integrated check valve for controlling pressure below a certain threshold. This pump preload valve is particularly suitable for use with control pumps such as the AVSO with SYDFE adjustment, where it is necessary to manage flow at operating pressures less than the specified bar limit and only internal pilot fluid is available for adjustment. It has been engineered to provide both preload and maximum pressure limitation functionalities. The SYDZ 0001-1X/250V028M is designed to be mounted directly onto the SAE pressure connection of variable displacement pumps in the AVSO series. It's important to note that this product's pressure limiting function serves as a safety feature and should not be used for continuous operation. Proper system bleeding upon commissioning is crucial for optimal performance. The unit comes in various sizes and supports a maximum operating pressure of up to a certain bar level, ensuring versatility across different applications while maintaining safety standards through its non-adjustable, factory-set features.
