Abstract
A valve assembly that generally includes a valve body defining an inlet, an outlet and a fluid flow path between the inlet and the outlet, a valve seat disposed in the fluid flow path of the valve body between the inlet and the outlet, a disc movably supported in the valve body between an open position and a closed position, an actuating mechanism for selectively moving the disc between the open position and the closed position and a valve trim provided on the disc. The valve trim defines a plurality of apertures providing a semi-tortuous fluid flow path for modifying fluid flow through the valve trim when the disc is in the open position. When the disc is engaged with the valve seat in its closed position, the apertures are blocked to close the fluid flow path.
