Abstract
A valve body with a diverted flow passage extending between the inlet and the outlet is provided with a closure element that is mounted between the inlet and outlet and movable between first and second lift points for regulating fluid flow through the passage. A baffle disposed in the flow passage intermediate the first and second lift points alters one or more flow characteristics of the fluid to improve the efficiency of fluid flow through the valve. In a right angle body valve, the baffle takes the form of a plate with an aperture positioned concentrically with the inlet passage and the valve closure element. A top plane surface of the baffle plate is positioned below the centerline of the outlet and is perpendicular to the centerline of the inlet. The baffle separates turbulent areas of flow in the passage so that the pressure and flow of fluid exiting the valve are more uniformly distributed over the entire outlet. In modified forms of the invention, the baffle shape, position and aperture are matched with the flow constraining structure to produce optimum flow through the structure. The invention may be employed in any structure where intersecting flow paths meet such that the direction of fluid flow is changed between the structure's inlet and outlet.
