Fluid system components with thermal conditioning passages

A flow control device comprising:

• a body including a flow passage extending axially along a primary axis between a first end port and a second end port, the flow passage defining a central cavity between the first and second end ports, with an interior surface of the flow passage being defined by an axially extending surrounding side wall of the body;
• and
• a flow control element disposed in the central cavity and movable to control fluid flow between the first end port and the second end port;
• wherein the body further includes a thermal conditioning passage disposed within the side wall, disconnected from the flow passage, and extending between a first conditioning port and second conditioning port, the thermal conditioning passage comprising:
• a first offset portion extending radially from the first conditioning port towards the flow passage,
• a first branch portion extending directly from the first offset portion circumferentially around a first portion of the interior surface of the flow passage in a first circumferential direction,
• a second branch portion extending directly from the first offset portion circumferentially around a second portion of the interior surface of the flow passage in a second circumferential direction opposite the first circumferential direction,
• a second offset portion extending radially from the second conditioning port towards the flow passage,
• a third branch portion extending directly from the second offset portion circumferentially around the first portion of the interior surface of the flow passage in the first circumferential direction,
• a fourth branch portion extending directly from the second offset portion circumferentially around the second portion of the interior surface of the flow passage in the second circumferential direction,
• a first connecting portion extending axially between end portions of the first and third branch portions, and
• a second connecting portion extending axially between end portions of the second and fourth branch portions.
