What type of valve should you get for your vessel?

You most likely picked a material of construction for your reactor or tank that is necessitated by your product characteristics and process requirements. Depending on your specifications, this can be anything from carbon steel, stainless steel, or PTFE to more exotic metals such as nickel alloy, Hastelloy, and titanium, or glass-lined steel for particularly corrosive applications. It is critical for the safety of your process that the material of your valve matches that of the vessel it is installed on. For example, if you use a glass-lined steel vessel because of a corrosive product that is not compatible with metals or plastic polymers, you must use a glass-lined valve. After all, you don’t want what’s going through your valve to go through your valve!
