The Bosch Rexroth SYDZ 0001-1X/250V140M (R900560526) is a high-quality pump preload valve designed to enhance the performance and reliability of control pumps, particularly the AVSO series with SYDFE adjustment. This component is engineered to be effective within a specific pressure range, ensuring that the preloading is maintained up to a certain bar level. Beyond this level, its integrated preload valve opens completely, allowing for the free flow of fluid when the operating pressure in port P exceeds the designated bar threshold. The model comes with an integrated pressure relief valve which is factory-set based on the ordering code provided in the type key, ensuring safety by limiting maximum system pressure. Additionally, it features an integrated check valve that can manage pressure control for operations below a specified bar level. It's important to note that this product's pressure limiting function serves as a safety measure and should not be used for continuous operation. Proper system bleeding is required during commissioning to avoid any operational issues. The SYDZ 0001-1X/250V140M pump preload valve boasts easy installation, as it is directly fastened at the SAE pressure connection of variable displacement pumps. With its robust design and integrated features for preload and maximum pressure limitation, this Bosch Rexroth valve ensures efficient and safe control of pump flow in hydraulic systems. The device's size and maximum operating pressures are clearly outlined in its specifications to match various application requirements, making it a reliable choice for managing hydraulic pump operations within specified parameters.

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).
