The Bosch Rexroth SYDZ 0001-1X/300V045M (R900560849) is a meticulously engineered pump preload valve designed to ensure optimal pressure preloading within a specific pressure range. It incorporates a safety feature through an integrated pressure relief valve which is preset at the factory, detailed in the ordering code, to limit the maximum pressure. This valve also includes an integrated check valve for regulating pressure under a certain threshold, enhancing its control capabilities. This model is particularly suitable for applications where controlled flow from control pumps like the AVSO with SYDFE adjustment is required at operating pressures below the specified bar limit, utilizing only internal pilot fluid for adjustments. The SYDZ 0001-1X/300V045M stands out by offering both preload functionality and maximum pressure limitation within its compact design. It is designed to be directly mounted onto the SAE pressure connection of variable displacement pumps in the AVSO series, facilitating ease of installation and maintenance. It's crucial to note that while this pump preload valve provides a critical safety function by limiting pressure, it is not intended for use under continuous operation in high-pressure conditions. Proper system bleeding upon commissioning is essential to maintain its integrity and performance. With its specific size and maximum operating pressure capacity, this Bosch Rexroth pump preload valve represents precision and reliability for hydraulic systems requiring meticulous control of pump flow under predefined conditions.

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).
