***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 ZSF50F1-1-1X/M/01D00 (R900528013) is a pilot-operated check valve in a sandwich plate design that is part of the ZSF NG component series. This model is specifically designed to be used with directional valves and has the capability to integrate an optional high-pressure connection NG. The valve features an integrated throttle check valve suitable for sizes NG6, NG10, and NG16. This model can handle a maximum operating pressure of 350 bar and allows for a maximum flow rate as per its specifications. The ZSF50F1-1-1X/M/01D00 is engineered for precise performance and reliability in controlling the flow of hydraulic fluid within a system. It is important to note that when using this valve, a nozzle must be ordered separately and installed in channel P of the upstream directional valve. The diameter of the nozzle should be selected based on the prefill valve size, as indicated in the schematics provided by Bosch Rexroth. Failure to comply with this requirement may result in increased dynamic loads that could negatively impact the operating time of the system. Users must ensure that they adhere to these guidelines to maintain optimal functionality and longevity of the valve. This product's design allows it to be an essential component for various hydraulic applications where backflow prevention or controlled flow is necessary. Its robust construction ensures it can meet the demands of heavy-duty operations while maintaining precise control over hydraulic systems.

Pilot operated check valve in sandwich plate design Directional valve set-up, optional High-pressure connection (NG32 … 160) Integrated throttle check valve (NG50, 63, 80 and 200)

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.
