Jet Co-flow Valve Tray's (JCV tray, Chinese Patent ZL00105902.5) valve is fixed on the tray with retainer tabs. The valve plates encased in a cage can move up and down in the gas slots.
JCV Tray's operation description:
(1) When lower than loading limit, the valve plate rests on the tray deck.
Gases flow through the small hole of valve plate only and distribute by
the valve cage into the liquid.
Comparing to normal valve, this valve is not easy fall off or locked. It has high loading range about 1:6. Through this range the pressure drop and tray efficiency remain almost constant.
The tray hole diameter is 50mm. JCV Tray's valve perforation density and distributing can be designed similar to normal valve tray.
The pressure drop and efficiency curves of JCV Tray are given below.
