Designing a valve that performs consistently in the cryogenic temperatures, high pressures, and thermal cycling of LNG is one tough job. But choosing the right seal can make it a lot easier. This presentation examines the relationship between seal choice and LNG valve performance, and it addresses important design criteria, such as material selection, seal lip geometry, and energizer force. It also suggests some ways to avoid common sealing mistakes that may be costing you time, money, and market share.
