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.
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
