***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth ZSFW125F0-1-2X/M/01 (R901103025) is a pilot-operated check valve in a sandwich plate design that exemplifies precision engineering for hydraulic applications. This particular model, part of the Type ZSFW NG series, is designed without predecompression and features a built-on directional valve. The control spool operates in a vertical direction, ensuring smooth and efficient operation for various hydraulic functions.
The ZSFW125F0-1-2X/M/01 valve can be equipped with an optional high-pressure connection NG and comes with an integrated throttle check valve suitable for sizes NG 6, 10, and 12. It belongs to the component series X, which signifies the latest development stage with improved performance characteristics. The maximum operating pressure capability of this model reaches up to 315 bar, while it can handle a maximum flow rate of up to 120 liters per minute.
This model also allows for the separate ordering of a directional valve type WE as an additional setup option, offering flexibility for specific system requirements. Its design is optimized for high reliability and durability in various hydraulic systems where precise fluid control is essential. With its robust construction and advanced features, the Bosch Rexroth ZSFW125F0-1-2X/M/01 check valve is an integral component for ensuring efficient and safe hydraulic operations across multiple applications.

Important information on hydraulic fluids: For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant – containing water: Maximum pressure differential 210 bar, otherwise, increased cavitation erosion Life cycle as compared to operation with mineral oil HL, HLP 30 … 100% Maximum hydraulic fluid temperature 60 °C Bio-degradable and flame-resistant: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system. |
