The invention provides a flow and fluid conditioning pressure reduction valve or device, comprising an inlet and an outlet, the valve or device is distinctive in that it comprises at least one relatively long flow bore conduit shaped as a spiral or a spiral arranged on the surface of a cone or frustum. Each spiral shaped conduit includes at least one, preferably at least three rotations and each spiral shaped conduit preferably is closely packed; the conduit has been arranged between the inlet and the outlet, has reduced flow cross section area, and the length, the cross section area and the number of the spiral shaped conduits in line determine the pressure reduction of a given fluid at a given flow rate. |
