Floating Valve Tray Floating valve tray (Equal to Sulzer BDH Tray) is 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.

Unique rectangular-shaped valves Valves oriented parallel to liquid flow direction No liquid flow under valves Minimize weeping due to lateral vapor release Improved turndown ratio compared to round valves Improved efficiency/capacity profile compared to conventional round valve trays Wide legs and lack of valve rotation reduce damage and wear Design allows for top side valve replacement Available range of valve lifts and weight allow for optimal design
