Alloy 20 Valves

Alloy 20 & 31 valves for Corrosive Petrochemical Applications

Looking for a valve in this exotic alloy? Find it in the following configurations: Ball, Butterfly, Cast, Check, Control, Cryogenic, Custom made, Foot, Forged, Gate, Globe, Needle, Plug, and Safety relief, as well as Strainers.

Alloy 20 valves are often used in high concentration acidic environments, particularly nitric and sulfuric acid. Such material is commonly known as A20 or as Carpenter 20 in other circles Alloy 31 valves are used in ore extractor systems and offers excellent crevice and pitting corrosion resistance in neutral and aqueous acid solutions.
