Diffuser is defined as “A device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. Delta T’s unique diffuser plate butterfly valve does that by incorporating a spherical edged disc with the diffuser plate to direct and diffuse the flowstream. This optimizes the ability to control flow and minimizes noise, cavitation and damaging high velocity jets of fluid. In the first 30° of rotation, when pressure drop is the highest, the spherical edged disc constrains the flow, directing it through the diffuser to minimize the potential for damaging flow conditions.
