Metal Floating Valve
1. Big operating flexibility
Owing to valve slice can go up and down freely, it can adjust the change of gas's lacuna. Meanwhile, it can also keep high separation efficiency under the circumstance of frequent change of liquid loading.

2. High separative efficiency
In practical application, the efficiency of Tower-board can up to 60-70%. And it can also keep the high separative in low loading. Because separative efficiency is high, its performance improves correspondingly.

3. Big handling ability
Because floating valve's arrange in tower is very compact, it can increase rate of pore. In addition, air current enter liquid layer for horizontal direction. It can increase production capacity and gas-flow rate.

4. Low pressure drop
Owing to one shrink, expand and swerve when gas passing through floating valve, its pressure drop is lower than Bubble cap's. In atmosphere tower, each column plate's pressure drop is only 3-5 mm mercury.
