ABSTRACT:
A fluid control valve suitable for pressure reducing service. A valve is provided with a fixed cage member containing an internal passageway communicating with a cage inlet and outlet. A movable valve plug is slidably mounted within the cage member and contains an internal plug passageway. A fluid flow path is provided through the plug assembly and through the cage internal passageway so that multi-stages of pressure reduction are obtained. The provided fluid flow includes a combination of axial, outwardly radial, inwardly radial flows and a flow through the internal passageway of the plug assembly in order to obtain the required multiple pressure drops. The restricted flow passages at each stage are large enough in size so that any particulate in the fluid will pass out without plugging up the passages in the valve trim.
