Control valve

Abstract

This article relates to a control valve, which makes it possible to adjust the flow rate in a flow path when a high-temperature fluid flows. The control valve of this article has multiple cooling fins on the neck portion of the bonnet. The flange portion of the bonnet has a rectangular outer shape in a plan view, and the cooling fins have a circular outer diameter, with multiple circular cooling fins arranged in parallel at predetermined intervals on the bonnet. The cooling fin closest to the body side of the bonnet has the smallest outer diameter of the other cooling fins and is circular in shape, and is located so as not to interfere with the bolts and nuts that are fastening members used to secure the body and bonnet together. Therefore, the cooling fin closest to the body side of the bonnet does not get in the way during assembly work.
