36-Inch-High Temperature Exhaust Valve
Turning an extreme situation into a plug-and-play assembly.
In 2011, JA Moody was contacted by a US shipyard to provide a solution for an existing engineering problem onboard a newly designed Navy ship. The conditions on the vessel and what needed to be done were extreme. The application was Engine Room exhaust.
JA Moody had to overcome:
- 570C (1058F) design temperature
- Engine back-pressure 30 mBar
- Shock-hardened service (Grade B)
- MOV electric operation with heat shields to protect the motor
JA Moody’s engineering team worked closely with sub-tier contractors Emerson/Vanessa and Curtiss Wright/Nu-Torque to produce a plug-and-play assembly.
Plug-and-play items were produced and delivered, replacing a failed design by a competitor, and placed on the next 17 ships.

No mechanical or functional issues were reported despite these extreme conditions.
