The Bosch Rexroth SYDZ 0001-1X/300V071M (R900562156) is a meticulously engineered pump preload valve designed to enhance the performance and safety of hydraulic systems. This valve is specifically tailored to work with control pumps such as the AVSO with SYDFE adjustment, ensuring that flow can be effectively controlled at operating pressures below a specified bar limit, utilizing only internal pilot fluid for the adjustment process. The SYDZ 0001-1X/300V071M features an integrated preload function and a factory-set, non-adjustable maximum pressure limitation, which corresponds to the specifications outlined in the ordering code. The product's design includes a check valve that permits pressure control within a certain range under the defined bar limit. Additionally, it comes equipped with a pressure relief valve for capping the maximum pressure, thereby safeguarding against overpressure conditions. This integrated safety mechanism serves as a precautionary feature and is not intended for continuous operation; it's important to note that upon initial setup, bleeding of the system is required. This particular model boasts compatibility with variable displacement pumps and can be directly mounted onto the SAE pressure connection of such pumps as detailed in Bosch Rexroth documentation RE 92XXX and RE 93XXX. With its robust construction, this pump preload valve is capable of handling maximum operating pressures up to several hundred bars. To summarize, the Bosch Rexroth SYDZ 0001-1X/300V071M offers precision control for hydraulic systems requiring regulated flow at lower pressures while incorporating essential safety features to prevent system overloads. Its integration into compatible hydraulic circuits ensures reliable and efficient operation tailored to specific application needs.

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.

technical illustration-R900562156-The pump preload valve SYDZ 0001 if the flow of control pumps A10VSO with SYDFE adjustment has to be controllable at an operating pressure of less than 12 bar and only internal pilot fluid is available for the adjustment. 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).
