Spring-energized seals are high-performance sealing devices widely used in API 6A gate valves, API 6D ball valves, control valves, and LNG applications. They consist of a polymer jacket (typically PTFE or PEEK) that partially encapsulates a corrosion-resistant metal spring energizer. This design creates a pressure-assisted, spring-energized sealing device that delivers exceptional performance under extreme conditions.
