Material Of Monel Check Valves


Monel alloy is a Nickel alloy material with the addition of:

  • Copper (Cu) 

  • Silicon (Si) 

  • Manganese

These materials are also known as Monel Alloy 400 and Monel Alloy K500


Material Features: 

Monel alloy has an excellent anti-corrosion performance in the reducing acid medium, especially have excellent corrosion resistance in high-temperature hydrogen fluoride and hydrofluoric acid solution, and resistant to any density of hydrofluoric acid solution corrosion. Mainly applies in high-temperature hydrogen fluoride gas and hydrofluoric acid solution condition, and its corrosion resistance is better than copper-based alloys when used in seawater.

Cautions Of Monel Check Valves


  • Ease of manufacture: trade-off between castability and weldability 

  • Pitting can be a problem at low velocities 

  • Don’t be used as the trim of austenitic stainless valves

  • P/T rating class 300=600 psi CWP 

  • Cost effectiveness need consideration


Application Of Monel Check Valves


  • Petrochemical plant

  • Refinery

  • Power plant

  • Water treatment plant

  • Marine exploitation 


Additional Uses & Comments Of Monel Check Valves


  • Variety of wrought/ bar specifications available, good for trim material. Excellent strength from K500 

  • Reasonable castability with the suitable design and higher Si content 

  • Weldable with lower Si content 

  • Excellent for hydrofluoric & other acids (Exclude nitric acids)
