ABSTRACT:
A control valve for dissipating the energy of a high pressure flowing media, the apparatus comprising a valve body having an internal cavity, an inlet and at least one outlet, the inlet, outlet and cavity being in communication to form a flow path through the body of the valve, a plurality of helical springs being arranged one within the other and disposed in the cavity with the convolutions of the innermost of the springs defining an axial fluid media pathway in open communication with the inlet, there being an actuator operable externally of the body for selectively effecting axial, reciprocal movement of the convolutions of the springs whereby the axial spacing between the convolutions of the springs is altered to control the fluid media flow from the pathway through the spaces between the convolutions to the outlet.
