Trays are used in mass transfer operations where pressure drop limitations are not critical. They are mainly used in high-pressure distillation operations. However, there are a few atmospheric, moderate pressure, and vacuum operations where trayed towers are used. Trays are available in segmental or cartridge type construction to suit our customer`s requirements.
Valve trays are flat perforated plates with downcomers where the perforations are covered by discs called valves. Valves are available in various designs to meet different process requirements. Valve trays offer many advantages over other conventional trays. They provide higher tray efficiencies and higher capacity when compared to bubble cap trays and higher turndown ratios when compared to sieve trays.
