- Specialised rectangular valves
- No liquid flow under valves
- Excellent turndown ratio
- Very good efficiency and capacity profile
These trays are provided with either round or rectangular floating valves. Valves are floating due to vapour flow from the underneath This maintains a near constant pressure drop with respect to variation in vapour flow rate. Due to this characteristic valve trays sustains higher tray efficiency. They are generally used in applications involving high turndown ratio.
Floating valve trays are provided with either moving round valves or the unique rectangular shaped valves. On account of their ability to control vapour flow, they provided higher effifiency over wider operation range.
