The Metal Floating Valve Tray is a proven and versatile column tray technology that has become the standard choice in distillation, absorption, and stripping services worldwide. Each tray deck is fitted with hundreds of precisely punched holes, each covered by a free‑floating metal valve. As vapor flow increases, the valves lift and open a larger flow area, and when the vapor rate drops, the valves settle back down, reducing the opening. This self‑regulating mechanism ensures stable, efficient gas‑liquid contact across an extremely wide operating range. With its high capacity, low sensitivity to fouling, and the ability to handle both clean and dirty services, the Floating Valve Tray is ideal for revamp projects and new installations in refining, petrochemical, chemical, and gas processing plants.

Product Highlights

• Wide Turndown Ratio: Self‑adjusting valves maintain excellent tray efficiency from 30% to 110% of design load, achieving a turndown ratio of up to 3:1 – far beyond that of fixed sieve trays.
• Stable Operation at Low Rates: At low vapor loads, valves remain partially closed, maintaining sufficient pressure drop to prevent liquid weeping and ensuring stable gas‑liquid dispersion across the entire tray deck.
• High Capacity & Low Pressure Drop: Full‑open valve design and optimized valve layout maximize throughput while minimizing pressure drop, often reducing column diameter and energy costs compared to bubble cap trays.
• Excellent Anti‑Fouling & Anti‑Plugging: The floating valve's constant movement and self‑cleaning action prevent solids, tars, and polymers from accumulating on the tray deck, extending run length in fouling services.
• Proven F1 & V1 Standard Valves: The classic F1 round valve and V1 rectangular valve are available from stock in large quantities, with well‑established hydraulic performance data enabling reliable, predictable designs.
• Robust Construction: Fabricated from 304, 316L, or carbon steel (and alloys), the all‑metal valve units are mechanically durable, corrosion‑resistant, and can operate at temperatures up to 450°C without deformation or sticking.
