A cross opening, flap valve, fall tray developed in Hungary operates with high efficiency under extreme load fluctuation, has a low pressure drop, and is a low power consumer. The tray consists of three elements (Fig. 1): the suspending shaft (1), the flap (2) which controls the gas and/or liquid stream, and the supporting bar (3) which limits the opening of the flap. Flap elements can be positioned on the suspending shafts in such a way that one element or groups of elements can turn clockwise while another group turns counterclockwise. The elements can also be positioned so that they form alternately clockwise and counterclockwise opening rows. Trays can be assembled into blocks of appropriate size (Fig. 2). A block needs no special adjusting because its construction is not sensitive to levelling, contrary to other tray types. In operation, the flap elements open according to the load of the light phase, generally gas or vapor, flowing upwards. The heavy phase (liquid) flows down. At any point between fully open and fully closed, one phase automatically determines the quantity of the other. The equipment is self-controlled. The flaps also drive the flowing fluid in cross-directions alternately by rows. This results in turbulent flow regardless of how high or low the load.
