Abstract

A valve assembly including a valve body defining an inlet, an outlet, a fluid flow path, and a chamber. A control element is disposed in the chamber and in the fluid flow path, and is rotatable by a valve stem about a pivot axis between an open position and a closed position. A flow conditioner coupled to the valve body and including a first end, a second end, and a plurality of channels extending between the first end and the second end. The plurality of channels are in flow communication with the fluid flow path of the valve body when the control element is in the open position. A plurality of walls separate the plurality of channels and include a first thickness and a second thickness different than the first thickness.

Dependent claims

A valve assembly comprising:

a valve body defining an inlet, an outlet, and a fluid flow path connecting the inlet and the outlet;
a valve port disposed in the fluid flow path;
a valve stem disposed in the valve body;
a control element disposed in the fluid flow path, the control element operatively connected to the valve stem such that the control element is rotatable by the valve stem about a pivot axis between an open position, in which the control element permits fluid flow through the valve port, and a closed position, in which the control element seals the valve port;
a flow conditioner coupled to the valve body and including a first end adjacent to the control element, a second end adjacent to the outlet, and a plurality of channels extending between the first end and the second end, the plurality of channels in fluid communication with the fluid flow path of the valve body when the control element is in the open position;
and
the flow conditioner further including a plurality of walls separating the plurality of channels, a first wall separating at least two channels having a first thickness and a second wall separating at least two channels having a second thickness different than the first thickness;
wherein a portion of the first end of the flow conditioner is convex;
wherein the pivot axis of the valve stem intersects a portion of the flow conditioner.
