  "term": "Expanding gate valve",
  "field": "Oil and gas",
  "definition": "A type of gate valve that uses a two-piece gate assembly designed to expand and create a tight seal against the valve seats when in the fully closed position. This expansion provides a positive, bubble-tight shutoff, even in high-pressure applications. Expanding gate valves are often used in pipelines for isolation where a reliable seal is paramount, such as in custody transfer metering stations.",
