Abstract
A flow control device includes a body and a flow control element. The body includes a thermal conditioning passage disposed within a side wall, disconnected from a flow passage, and extending between a first conditioning port and a second conditioning port. The thermal conditioning passage has a first portion extending circumferentially around a first circumferential portion of the interior surface of the flow passage, a second portion axially spaced from the first portion by a first axial U-shaped bend and extending circumferentially around the first circumferential portion and a second circumferential portion of the interior surface of the flow passage to form a first circumferential U-shaped bend, and a third portion axially spaced from the second portion by a second axial U-shaped bend and extending circumferentially around the second circumferential portion of the interior surface of the flow passage. The thermal conditioning passage further including a radial passage connecting a central portion of the first circumferential U-shaped bend with one of the first and second conditioning ports.
