***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 ZSF125F0-1-2X/M/01 (R901081775) is a pilot-operated check valve in a sandwich plate design that offers versatility and reliability for hydraulic systems. This model is part of the component series X, which signifies its advanced design and capability to handle high-pressure applications up to a maximum operating pressure of 350 bar. The ZSF125F0-1-2X/M/01 is engineered to ensure a maximum flow rate, providing efficient control over the flow of hydraulic fluid in various applications.
This valve features an integrated throttle check valve for sizes NG6, NG10, and NG16, which allows for precise control of the flow passing through the valve. It also enables optional directional valve setup, ensuring flexibility in system design and application. The high-pressure connection NG25 underscores its suitability for use in systems with higher flow demands.
For optimal performance, it's crucial to note that when using this model with size 25, a nozzle must be separately ordered and provided in channel P of the upstream directional valve. The diameter of this nozzle must be carefully selected according to the prefill valve size as indicated in the schematics provided by Bosch Rexroth. Failure to comply with this requirement could lead to increased dynamic loads that may adversely affect the operating time of the system.
The Bosch Rexroth ZSF125F0-1-2X/M/01 is designed for those seeking a robust and adaptable solution for controlling fluid dynamics in complex hydraulic systems. Its combination of high-pressure capabilities, integrated throttle check functionality, and optional directional valve configurations make it an essential component for ensuring efficient and reliable operation across various hydraulic applications.

This product is eligible for factory repair.
Notice:
With size 32, 40, 100, 125, 160 a nozzle (separate order) must imperatively be provided in channel P of the upstream directional valve. The nozzle diameter is to be designed according to the prefill valve size (see "Schematics").
In case of non-compliance, increased dynamic loads may occur having detrimental effects on the operating time.

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. |
