Trapezoidal Valve Innovation
Guided Metal Conventional Valve Trays feature patented trapezoidal valves that redirect gas flow at acute angles to liquid movement, creating synergistic forward thrust. This Tianjin University-developed design slashes tray pressure drop by 15-20%, extends turndown flexibility (33% lower gas load limit + 20% upper limit), and eliminates stagnant zones in refinery fractionators and petrochemical towers.
Performance Advantages vs. F1 Valve Trays
Parameter | Guided Trapezoidal Valve | F1 Conventional Valve |
---|---|---|
Pressure Drop | ▼ 15-20% | Baseline |
Gas Load Lower Limit | ▼ ~33% | Baseline |
Gas Load Upper Limit | ▲ 10-20% | Baseline |
Turndown Ratio | 8:1 | 5:1 |
Stagnation Risk | Near-zero | Moderate |
