Valve Tray Column | OperatiX – 14
The Valve Tray Column OperatiX – 14 is a glass column, 750mm high and 50mm in diameter, with 7 trays. This Valve Tray Column uses self-adjusting liftable valve caps to control vapor flow across a wide range of flow rates. It demonstrates anti-weeping design through dynamic orifice area adjustment. The column includes 3 input ports and offers both stationary and movable valve configurations.
The Valve Tray Column OperatiX – 14 uses liftable caps that self-adjust in accordance with vapor flow to cover the apertures in its trays. This Valve Tray Column prevents liquid from dripping at low vapor rates by closing off the tray valves. It expands the region open to vapor flow as the vapor rate rises.
Product Overview
Liftable caps that self-adjust in accordance with the vapor flow are used to cover the apertures in valve trays. By closing off at a low vapor rate, tray valves or caps prevent liquid from dripping from the tray. The valve lifts as the vapor rate rises, expanding the region that is open to vapor flow.
Vapor flow can change the apertures of valve trays, allowing the trays to function over a wide range of flow rates with great separation efficiency and significant flexibility. This is a key characteristic of the Valve Tray Column design.
Since the valve tends to close as the gas flow decreases, the valve plate is made to minimize this drainage, or “weeping,” with the total orifice area shifting to maintain a dynamic-pressure balance across the plate. The trays’ valves can be stationary or movable. The movable valves adjust themselves in response to the vapors streaming up through the tray holes, while the fixed valves remain open permanently.

Construction and Design
The Valve Tray Column OperatiX – 14 is built as a glass column, 750mm in height and 50mm in diameter. It contains 7 trays, each fitted with 1 valve. The valves are liftable caps that cover the apertures in the trays. At low vapor rates, the valves close off to prevent liquid from dripping. As vapor rate rises, the valve lifts, expanding the region open to vapor flow. The valve plate is designed to minimize weeping by shifting the total orifice area to maintain a dynamic-pressure balance across the plate. Valves can be stationary or movable, with movable valves self-adjusting to vapor flow and fixed valves remaining open permanently. The column includes 3 input ports.
Q: What is the Valve Tray Column OperatiX – 14 used for?
A: It is used to demonstrate vapor-liquid contact using self-adjusting valve trays that respond to changes in vapor flow rate.
Q: How many valves does each tray have?
A: Each tray has 1 valve.
Q: How do valve trays prevent weeping?
A: The valve plate minimizes drainage, or weeping, by shifting the total orifice area to maintain a dynamic-pressure balance across the plate as gas flow decreases.
Q: What is the difference between stationary and movable valves?
A: Movable valves adjust themselves in response to vapors streaming up through the tray holes, while fixed valves remain open permanently.
Q: What material is the column made of?
A: The column is made of glass.
