The Bosch Rexroth SYDZ 0001-1X/200V028M (R900537400) is a high-quality pump preload valve designed for precise pressure control within hydraulic systems. This component is engineered to be effective within a pressure range up to the specified bar limit. Beyond this threshold, the preload valve opens completely when the operating pressure in port P exceeds the preset bar level. To safeguard against excessive pressure, the SYDZ 0001-1X/200V028M includes an integrated pressure relief valve that is factory-set and non-adjustable as indicated in the ordering code. Additionally, an integrated check valve is available to maintain pressure control below a certain bar level. It's important to note that this pressure limiting function serves as a safety feature and is not intended for continuous operational use. Proper system bleeding is required upon commissioning to ensure optimal performance. The SYDZ 0001-1X/200V028M is particularly suitable for scenarios where flow control of AVSO variable displacement pumps with SYDFE adjustment is necessary at operating pressures less than the specified bar limit using only internal pilot fluid for adjustment. The design incorporates both preload and maximum pressure limitation features, providing a reliable solution for managing hydraulic pump operations. This pump preload valve is directly mountable onto the SAE pressure connection of variable displacement pumps AVSO as detailed in Bosch Rexroth's documentation (RE series). The product comes in sizes 10, 20, and 30, with a maximum operating pressure capacity of up to several hundred bars, ensuring it can handle demanding applications while maintaining system integrity and performance.
