The Bosch Rexroth SYDZ 0001-1X/250V045M (R900562331) is a specialized pump preload valve designed for precise pressure control in hydraulic systems. This robust component ensures that the pressure preloading is effective within a specific pressure range, up to a certain bar level. When the operating pressure at port P exceeds this threshold, the preload valve opens completely, allowing for the system to adapt to changing conditions. An integrated pressure relief valve, which is factory-set and non-adjustable as per the ordering code, provides an additional layer of safety by limiting the maximum system pressure. The SYDZ 0001-1X/250V045M includes an integrated check valve that enables pressure control below a certain bar level. This feature is critical for systems where consistent and accurate low-pressure operation is necessary. It's important to note that the pressure limiting function of this component serves as a safety measure and is not intended for continuous operation. This pump preload valve is particularly suited for use with Bosch Rexroth's variable displacement pumps, such as those in the AVSO series with SYDFE adjustment, when only internal pilot fluid is available and there's a need to control flow at operating pressures less than a specified bar level. The unit can be directly mounted onto the SAE pressure connection of these pumps, ensuring seamless integration into existing hydraulic circuits. Upon installation, it's essential to bleed the system properly to ensure optimal performance of the valve. The SYDZ 0001-1X/250V045M comes in various sizes and can handle maximum operating pressures up to a defined limit in bar, making it versatile enough to meet diverse hydraulic requirements while maintaining safety and efficiency within your hydraulic applications.
