Cast valve body made of ADI (austempered ductile iron)

[CptMaaB]

I would be interested to know if there are valve manufacturers or end users, who use ADI casted material in their valves or plants.
I have not found any reference to this material in the corresponding valve standards (ASME B16.34 / DIN EN 1092).
The only thing I have found are check valves whose bodies are casted from this material.
I would be very interested to know your experience and knowledge with this cast material.

Thanks in advance, Cpt.!

Is there noone out there who can give an answer!?
Maybe ADI is not common, eventually the material number 5.3400 (EN-GJS-800-10) will help to get some answers.

There is hundreds if not more manufacturers making ductile iron valves. Since it is an iron material, it does not appear in the steel valve standards that you mention. Ductile iron valves are in standards EN 1092-2, ASME B16.42. Ductile iron is very common for lined plug and ball valves, concentric disc type butterfly valves. Very common material for water works industry.

Thanks for reply bcd.
I`m common with ductile iron valves, we manufacture alot of them, but i never saw a valvebody made from ADI material.
Maybe because its to expensive.
But i will have a deeper look into the ASME B16.42, maybe i can find something.

Agree with bcd.

Also common for valves for waste water, and for gate-valves bodies. Search for European (German or UK producers) to check details for body material and surface protection.

I agree that the most common material is EN-GJS-400-18 but that is not ADI (austempered ductile iron casting).
