Rotary valve for distribution of flow of control, apparatus of heat exchange and mass per evaporacao, process to control the rate and distribution of water in such an apparatus, and,Cross flow cooling tower
A rotary flow control balancing valve, in particular for use with an integral predistribution pan in gravity feed cross-flow cooling towers, comprising concentric movable and stationary portions (12,18), each portion being provided with holes (27). As the movable portion is rotated relative to the stationary portion the degree of alignment of the holes in the two portions changes, thus allowing for the control of fluid flow through the valve. The movable portion may be provided with locking means to fix the movable portion relative to the stationary portion.
