The Mark 74 provides long-term, leak-free performance when fugitive emissions are a primary concern. The Mark 74 offers exceptional bellows life with a valve stroke that is just a fraction of that of other rising stem valves. This means Jordan Valve can use a smaller formed bellows that has minimal movement during operation.
The Mark 74 controls fugitive emissions while reducing the risks associated with toxic, corrosive, explosive, and high temperature fluids.
