Dynamic Flow Control​​ F1 Metal Conventional Valve Trays feature circular valves with twist-locked legs that automatically modulate openings based on gas velocity. This self-adjusting design maintains optimal vapor-liquid contact across 4:1 turndown ratios while preventing valve detachment – delivering reliable efficiency in FCC main fractionators, NGL columns, and gas sweetening units. ​​Core Mechanism​​ ​​Component​​ ​​Funct

Engineered for Reliability​​ Metal Fixed Valve Trays feature permanently open valve units that deliver sieve-tray simplicity with enhanced vapor-liquid contact. By eliminating moving parts, they prevent wear/sticking while achieving 20-30% higher capacity and 6:1 turndown ratios versus sieve trays – ideal for fouling services like FCC main fractionators and PVC slurry strippers. ​​Performance Advantages vs. Sieve Trays​​ ​​Par

​​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
