The Bosch Rexroth SYDZ 0001-1X/300V028M (R900537404) is a sophisticated pump preload valve designed for specific hydraulic applications. This component offers precise pressure preloading within a range up to a specified bar limit, ensuring that the preload valve opens completely if the operating pressure in port P exceeds this threshold. To safeguard against overpressure situations, the SYDZ 0001-1X/300V028M features an integrated pressure relief valve that is preset at the factory and cannot be adjusted in the field. The model also includes an integrated check valve, which allows for controlled pressure management below a certain bar level. This pump preload valve is particularly suitable for use with control pumps like the AVSO with SYDFE adjustment when there is a need to manage flow at operating pressures below a designated bar value and only internal pilot fluid is available for adjustment. The product's design encompasses both preload functionality and maximum pressure limitation, providing users with a reliable safety mechanism to prevent continuous operation under excessive pressure conditions. It's important to note that upon installation, it is necessary to bleed the system to ensure proper function. The SYDZ 0001-1X/300V028M attaches directly to the SAE pressure connection of variable displacement pumps from Bosch Rexroth's AVSO series as indicated in their documentation (RE series). This unit comes in various sizes and supports maximum operating pressures up to a certain bar level as defined by its ordering code. Users can refer to this code to understand the specific limitations and capabilities of their particular model.
