摘要： An ANSI Leakage Class V control valve having consistent shut off characteristics with a reduced actuator force required to open and close the valve is provided. The trim arrangement of the control valve includes a valve cage having a multi-contoured inner surface. The multi-contoured inner surface can include a plurality of surfaces. The multi-contoured surface can include first, second, and third perimeter surfaces, and a first transition surface disposed between and coupling the first and second perimeter surfaces, and a second transition surface disposed between and coupling the second and third perimeter surfaces. The valve also includes a valve plug disposed at one end of a valve stem. The valve plug controls the fluid flow through the valve. The valve plug includes an opening through the plug for equalizing pressure across the valve plug. An annular channel is formed within a wall of the valve plug and is sized to accommodate a sealing ring. The sealing ring engages the second perimeter surface to form a fluid seal that substantially hinders fluid leakage through the valve.

摘要： A control valve having a shiftable valve plug includes a valve body having an inlet, an outlet, a flow passage extending between the inlet and the outlet, and defining a longitudinal axis, a generally cylindrical valve cage disposed within the valve body and sized to receive the valve plug, with the valve cage including at least one aperture comprising at least a portion of the flow passage, a portion of the valve cage disposed adjacent a portion of the valve body at an interface. A seal having a C-shaped cross section is provided and is disposed at the interface between the valve cage and the valve body, and a retainer is disposed adjacent the interface and positioned to secure the seal against movement along the longitudinal axis.

摘要： Fluid pressure reduction devices for use in gas and liquid handling systems are disclosed. An example fluid pressure reduction device includes a plurality of cylinders, each having an inner diameter surface and an outer diameter surface and a plurality of apertures that extend from the inner diameter surface to the outer diameter surface. The cylinders are arranged in a nested configuration so that a substantial portion of the inner diameter surface of one of the plurality of cylinders is in contact with a substantial portion of the outer diameter surface of another one of the cylinders. Portions of the apertures of one of the cylinders overlap at least portions of the apertures of another one of the cylinders to form a process fluid flow path.
