***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth SYDZ 0001-1X/200V045M (R900564353) is a highly specialized pump preload valve designed to provide pressure preloading within a specific pressure range. This valve is particularly effective up to the maximum threshold pressure, beyond which its integrated preload valve opens completely to ensure safety and system integrity. It comes with a factory-set, non-adjustable pressure relief valve for limiting maximum pressure as per the ordering code specifications. Additionally, the SYDZ 0001-1X/200V045M features an integrated check valve that enables pressure control below the threshold bar level. This precise control makes it suitable for applications where internal pilot fluid is available and where the operating pressure needs to be managed at less than the specified bar level. This pump preload valve is engineered for direct attachment to the SAE pressure connection of Bosch Rexroth's variable displacement pump AVSO. It ensures seamless integration and performance optimization when used in conjunction with these pumps, as indicated in documentation RE and RE. The size specifications of this model cater to diverse system requirements, while its design supports a maximum operating pressure of bar, signifying its robustness for high-pressure applications. Users are advised that this product's pressure limiting function serves as a safety feature and should not be used for continuous operation. Proper bleeding of the system upon commissioning is also recommended to maintain functionality and prevent any operational issues. In summary, the Bosch Rexroth SYDZ 0001-1X/200V045M (R900564353) is tailored for systems requiring controllable flow under specific conditions, offering both preloading capabilities and maximum pressure limitation in one integrated solution.

The pressure pre-loading is only effective within the pressure range up to 20 bar. If the operating pressure in port P1 exceeds 30 bar, the preload valve (1) is completely opened. For limitation of the maximum pressure, a pressure relief valve (2) is integrated in the pump preload valve which is fixedly set at the factory (see ordering code). An integrated check valve (3) that may be available allows for the pressure control in the range < 20 bar.

Notice:

The pressure limiting function is a pure safety function and not suitable for continuous operation!

Upon commissioning, the system is to be bled.

Only for separate order of the pump preload valve

For applications outside these parameters, please consult us!

The pump preload valve SYDZ 0001 has integrated preload and maximum pressure limitation. Notice: The pressure limitation is determined according to the ordering code (see type key) and is not adjustable. The pump preload valve SYDZ 0001 is directly fastened at the SAE pressure connection of the variable displacement pump A10VSO (see RE 92711 and RE 92714).
