Monel valves in petrochemical and trumpets?Did you know that the main two end uses of monel valves are world apart? One of the main uses of valves made of monel is in the petrochemical industry. Monel valves are particularly useful in oxygen service, as well as marine service in combination with aluminium bronze. This corrosion resistant alloy is of particular use in alkylation processes where hydrofluoric acid eats through most metals, bar monel and hastelloy.
Monel valves are also used in.... trumpets! Monel valves don't require being oiled frequently since oil evaporates faster on stainless steel compared to monel. The drawback: price!
