摘要
A gap control device that works with a plug on a valve assembly for use in high-temperature applications. The plug may include two parts and a compressible seal that, when compressed, engages with an adjacent wall of a cylinder or “cage” typical of a trim assembly. In one embodiment, the gap control device forms a hard stop that expands in response to high temperatures. This feature prevents excess over-travel between the two parts of the plug in the high-temperature applications so as to limit stress and wear on the compressible seal.
