The DN125 hydraulic shut-off valve used in a concrete pump truck pipeline plays a critical role in controlling the flow of concrete within the system. Its primary functions are as follows:

1. Flow Control:
   The hydraulic shut-off valve is used to start, stop, or regulate the flow of concrete in the DN125 pipeline. This ensures smooth operation during pumping and prevents unnecessary flow when the pump is not active.

2. System Safety:
   By allowing immediate shut-off of the concrete flow, the valve helps protect the pipeline and other components from overpressure or blockages, which can occur during operation.

3. Prevention of Backflow:
   The shut-off valve prevents backflow of concrete within the pipeline, ensuring efficient and controlled pumping in the desired direction.

4. Maintenance Support:
   During maintenance or repair of the pipeline or other system components, the hydraulic shut-off valve isolates sections of the pipeline, allowing safe and controlled access without affecting the rest of the system.

5. Operational Efficiency:
   The valve enhances the overall efficiency of the concrete pump truck by providing precise control over the flow of concrete, ensuring consistent delivery to the target area.
