    Abstract: A valve body, for use in a valve housing having an inlet and outlet, includes a spherical outer surface. A flow opening extends diametrically from one side of the outer surface to an opposing side. A plurality of flow control passageways extend from the outer surface into the valve body. The valve body is moveable relative to the valve housing between a closed position, a restricted flow position, and a free flow position. In the closed position, the flow opening and all of the plurality of flow control passageways are out of alignment with the inlet and outlet. In the restricted flow position, at least one flow control passageway is moved into fluid communication with the inlet and outlet to facilitate fluid communication therebetween. In the free flow position, the flow opening is moved into fluid communication with the inlet and outlet to facilitate fluid communication therebetween.

    Abstract: A fluid control valve includes a housing defining a fluid inlet and a fluid outlet. A valve seat is coupled to the housing and is positioned between the inlet and the outlet. The valve seat includes an end surface, seating surface extending from the end surface toward the seat axis, and a groove surface extends from the seating surface and defines a groove extending around the seat axis. The valve seat further includes an inner surface defining a central bore extending along the seat axis. A spindle is disposed within the housing and is reciprocally moveable between closed and open positions within the central bore of the valve seat. The spindle defines a longitudinal axis and includes an outer surface and a plurality of flow passages formed in the outer surface to prescribed lengths and extending in generally parallel relation to the axis of the spindle.

    Abstract: A cascade type trim for integration into control valve and having a valve stem and a valve cage which cooperate with each other to define a plurality of fluid passageway columns, each of which extend between a valve inlet and a valve outlet. Each fluid passageway column is collectively defined by a plurality of stem passageways and a plurality of cage passageways. The stem and cage passageways are brought in and out of alignment as a result of axial movement of the stem relative to the cage. In a first position, a first fluid passageway is open, while a second fluid passageway remains closed. In a second position, both the first and second fluid passageways are open, and yet in a third position, the first fluid passageway is closed and the second fluid passageway is open.

    Abstract: In accordance with the present invention, there is provided a multi-spindle spray nozzle assembly for a steam desuperheating or attemperator device. The nozzle assembly features a nozzle holder which accommodates two small, spring-loaded nozzles, each of which is adapted to produce a spray pattern of reduced cone angle (e.g., approximately 60°) in comparison to currently know nozzle designs. The two nozzles are positioned within the nozzle holder such that they diverge from the axis thereof as allows the spray pattern generated thereby to be effectively tilted into the flow of steam within a desuperheating device having the nozzle assembly interfaced thereto.
