ABSTRACT:
A valve assembly includes a valve body, a valve seat, and a valve plug. The valve body defines a flow path for a fluid. The valve plug is adapted for displacement between a closed position and an open position in the valve body. The valve plug includes a crown, a skirt and a protrusion. The crown is for sealingly engaging the valve seat when the valve plug is in the closed position. The skirt defines a flow path for accommodating the fluid when the valve plug is in the open position. The protrusion is substantially concentrically aligned with the skirt. Each of the skirt or the protrusion have a surface treatment for enhancing the flow of the fluid through the valve when in the one or more open positions.
