| The Ship Change Documents required to put new equipment on board ships are still going through the Navy's approval process. The valves are on hand for installation and at-sea testing -- two on the USS McCLUSKEY (FFG-41) soon, and two on an undetermined Carrier, depending upon availability. |

Problem:
| Temperature Regulating Valves are used to control the temperature of the water used to cool the electronics and radar cabinets. Ships have reported fluctuations of as much as 10 degrees off the set point, creating condensation and corrosion problems. Fluctuations also cause electronic components to fail prematurely. |
Solution:
| An electronically controlled temperature control valve has been tested on the DDG-51 class. This valve has eliminated condensation issues and reduced temperature variations to +/- 0.5 degrees. This project will extend and qualify the TCVs for a variety of applications (sizes, flows, water type, etc.) on other ship classes. |
Fleet Impact:
| Improved cooling water temperature control to shipboard electronics will reduce maintenance, not only on the valve itself, but also the electronics. It will also essentially eliminate the corrosion effects caused by the excessive condensation in some compartments. |
