Abstract: In accordance with the present invention, there is provided a dirty service valve including an axial trim which, as a result of its structural attributes and extended stroke length, provides increased Cv capacity relative to valve plug size in comparison to existing prior art designs. In accordance with one embodiment of the present invention, the axial trim integrated into the valve of the present invention is configured to provide a linear flow characteristic. In accordance with an alternative embodiment of the present invention, the axial trim may be configured to provide a non-linear flow characteristic which, coupled with the extended stroke length thereof, provides improved flow control in addition to increased Cv capacity. The axial trim possessing the above-described structural and functional attributes may also be integrated into an axial body or housing, thus making the use of rotary actuators in conjunction with the axial trim more feasible.

Abstract: An improved valve element for a spray nozzle assembly of a steam desuperheating device that is configured to spray cooling water into a flow of superheated steam in a generally uniformly distributed spray pattern. The valve element comprises a valve body and an elongate valve stem that is integrally attached to the valve body and extends axially therefrom. The valve body itself comprises a nozzle cone which is integrally connected to the valve stem, and defines an outer surface. Integrally formed on a bottom surface of the nozzle cone is a hub having multiple ribs protruding therefrom. Integrally connected to each of the ribs is a generally circular fracture ring. The fracture ring is disposed in spaced relation to the lower edge of the nozzle cone which circumvents the bottom surface thereof. In this regard, a series of windows are formed in the valve body, with each window being framed by a segment of the lower edge of the nozzle cone, an adjacent pair of the ribs, and a segment of the top edge of the fracture ring.

Abstract: A valve assembly comprising a rotary closure element which defines an axis of rotation and is selectively movable between a fully open position and a fully closed position. Mounted to and movable with the rotary closure element is an impedance assembly. The impedance assembly defines an inflow end and an outflow end, and comprises a plurality of tortuous passageways which extend from the inflow end to the outflow end. Also fully or partially defined by the impedance assembly is an enlarged flow opening which extends from the inflow end to the outflow end. The tortuous passageways and the flow opening are oriented relative to each other such that a portion of a flow through the valve assembly is directed into the tortuous passageways and a portion of the flow is directed through the flow opening when the closure element is in the fully open position.
