    Abstract: A control valve includes a valve body having a main valve passageway. A flow control assembly is positioned in the main valve passageway and includes a first control element, and a second control element rotatable relative to the first control element between a closed position, a first position, and a second position. In the closed position, the first and second control elements form a plug which prevents fluid flow through the main valve passageway. In the first position, the first and second control elements collectively define a first control passageway therethrough, and in the second position, the first and second control elements collectively define the first control passageway and a second control passageway therethrough.

    Abstract: In accordance with the present invention, there is provided a control valve comprising there is provided a control valve comprising a valve body having a valve bonnet which is cooperatively engaged thereto. The body and the bonnet collectively define a housing which accommodates a valve trim comprising a flow control element and a complementary valve plug. The plug is attached to a reciprocally rotatable valve stem of the control valve. In the control valve, the reciprocal rotary movement of the valve stem of the valve through the packing area thereof, rather than the reciprocal liner movement of the valve stem through such packing area, is used to facilitate the reciprocal linear movement of the plug cooperatively engaged to the stem. The use of a rotary stem design instead of a liner reciprocating stem is operative to reduce fugitive emissions from the valve.
