Valve Tray

VE TRAYS which usually have a cost comparable to perforated trays, afford the widest operating ranges and greatest capacity. Considering the additional operating range and capacity of valve trays over perforated trays, it can be concluded that valve trays are actually lower on cost.

In many applications, vapor loading controls capacity. In many cases, valve trays may have as much as ten percent more capacity than perforated trays. Trays with valves comprised of three pieces (fixed caged, valve plate and orifice cover) have been proven very efficient for glycol dehydrators and other services with low liquid rates. In many cases these valve trays can effectively be utilized to replace bubble cap trays (which are considerably more expensive) for these low liquid rate services.
