## Summary description

Axial check valve for fluid systems by GRUNDFOS, designed for DN100 piping and rated PN2.5. The valve mounts on the inlet side to prevent backflow and protect pumps and system components. Suitable for use in water supply, circulation and industrial installations where a DN100 non-return solution is needed. Supplied as model 96615831.

## Long description

Axial check valve GRUNDFOS DN100 (inlet side), PN2.5, model 96615831 is a non-return valve designed for installation on the suction/inlet side of pumps and piping systems. Built for DN100 pipe size and rated PN2.5, the valve prevents reverse flow to protect pumps and other system components in water supply, circulation and industrial applications. The axial design minimises pressure loss and provides a compact solution for installations where backflow prevention is required at the inlet.
Advantages
The axial check valve provides reliable backflow prevention with low hydraulic resistance, helping to maintain pump priming and reduce water hammer. Its DN100 dimension and PN2.5 rating make it compatible with standard medium-pressure water systems. The inlet-side mounting simplifies installation near pump suction flanges and reduces the need for additional pipework. The valve construction is aimed at durability and stable operation under normal operating conditions.
Suitable for
 Water supply and distribution networks with DN100 piping
 Pump inlet/suction protection in circulation systems
 Industrial installations requiring inlet-side non-return valves
 Systems where minimal pressure drop across the valve is important
Key specifications
 Nominal diameter: DN100
 Pressure rating: PN2.5
 Type: axial check (inlet-side non-return valve)
 Application medium: water and compatible fluids used in circulation and supply systems
 Mounting position: inlet/suction side of pump or pipeline
How to use
Install the valve in the pipeline with correct flow direction oriented from inlet toward the pump suction, ensuring flange faces and gaskets are aligned and tightened to the recommended torque. Verify the pipeline is supported to avoid stress on the valve body. Before commissioning, flush the line to remove debris and inspect the valve for free movement of the internal disc or mechanism. Monitor the system during initial operation to confirm the valve closes properly under reverse-flow conditions and that no abnormal noise or vibration occurs.
Usage recommendations
Select the valve for systems matching DN100 and PN2.5 specifications and confirm material compatibility with the working fluid. Keep a routine inspection schedule to check for wear, leakage or buildup of debris. When replacing or servicing, follow manufacturer guidance for safe isolation of the pipeline and correct reassembly to preserve sealing and operational characteristics.
