Floating valves tray is a kind of tower tray which has many holes on the surface and there is a valve on each hole. When there is no upward gas phase, floating valves are closed on the tray. Floating valves, when gas phrase rises, will be opened by the impact of gas and their opening size will increase with the increase of the gas phase. Upward gas phrase, going through valve holes and being retained by floating valve plates, releases horizontally and laterally. Bubbling up from liquid layer, gas and liquid phases can fully make contact with each other to achieve an ideal heat and mass transfer effect. Due to their ability to control vapor flow, they provide a higher efficiency over a wider operating range than sieve trays.

Floating valve trays are used in applications where higher turndown ratios are required. They are also widely used in distillation, extraction, medical, petroleum, chemical, oil refining equipment and many other fields.
