Foss ball valve
Thread Content

HC refers to Hastelloy, a material that is slightly better than 316L and offers improved corrosion resistance

Fors’s valves are of poor quality; there are sand holes everywhere. . .
HC is a nickel-based alloy. The one on the second floor is incorrect
Foss valves are terrible; they’re full of sand
