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.
