Abstract
A valve arrangement comprises a valve housing, a valve seat and a valve plug. The valve housing defines an interior chamber and a flow opening for respectively receiving and discharging fluid. The seat ring is engaged to the valve housing and defines an angled seating surface and a spaced pair of channels positioned between the seating surface and the valve housing. The valve plug is axially slidable within the interior chamber and defines a valve plug seating surface configured at an angle complementary to that of the seat ring seating surface for creating a fluid-tight surface-to-surface seal. The valve plug further defines a spaced pair of projections configured to cooperate with respective ones of the channels such that disengagement of the valve plug seating surface from the seat ring seating surface defines a tortuous fluid path for reducing the velocity of the fluid flowing therethrough.
