Latest Patents

John Du's most recent patent is for a balanced plug valve with a contour wall. This innovative valve design features a contour-shaped wall that creates a gap with the edge of a balanced plug. Fluid can flow through an input port, through the balanced plug, through the gap, and out an output port. The contour's shape and the balanced plug's position relative to the wall significantly influence the modulation of fluid flow rates. The design allows for multiple variations in the contour dimensions, enabling a wide range of flow rate versus valve stroke relationships. Additionally, the balanced valve reduces friction forces on the plug, leading to smaller, more efficient, and economical valve actuators.
