The Bosch Rexroth ZSFW125F1-1-2X/M/01 (R901090317) is a pilot-operated check valve in a sandwich plate design, part of the ZSFW NG series, designed to ensure stable and efficient control in hydraulic systems. This model is characterized by its lack of predecompression and has a built-on directional valve with a vertical working direction for the control spool. It is tailored for applications that require precise flow direction control within a hydraulic circuit.
The ZSFW125F1-1-2X/M/01 features an integrated throttle check valve suitable for high-pressure connections in the NG size range. The directional valve type WE can be ordered separately and set up according to specific system requirements. It boasts a robust design capable of withstanding maximum operating pressures up to bar and can accommodate maximum flow rates of l/min, ensuring reliable performance under demanding conditions.
This model's component series X denotes its adherence to the latest standards in terms of both design and function, guaranteeing compatibility with contemporary hydraulic systems. Its precise engineering makes it an optimal choice for various applications where fluid direction needs to be controlled efficiently without compromising system integrity or performance. The Bosch Rexroth ZSFW125F1-1-2X/M/01 is a testament to high-quality engineering designed for durability and consistent operation over extended periods.

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. |
