AI Overview
API 6D helical spring seals are high-performance, spring-energized polymer seals (often PTFE) designed for severe-service ball valve applications, including cryogenic, LNG, and high-pressure oil and gas systems. They provide zero-leakage sealing by combining a high-load helical spring with a resilient jacket to resist low-temperature shrinkage and maintain consistent sealing force.
