Floating valve trays (Equal to Sulzer BDH Trays) are typically used in basic applications where higher turndown ratios are required. Due to their ability to control vapor flow, they provide a higher sustained efficiency over a wider operating range than sieve trays. Sulzer Chemtech offers conventional round valve trays in addition to its proprietary Float ValveTM trays, such as BDH, Snap-In and Caged valves.
