Industrial environments dealing with flammable and combustible materials require stringent safety measures, especially concerning valve performance under fire conditions. This is where the American Petroleum Institute (API) standards, specifically API 607 and API 608, come into play. These standards provide a framework for testing and certifying valves for fire safety, ensuring their integrity in extreme situations. What is API 607? API 607 outlines the fire test requirements for quarter-turn valves with soft seats, commonly used in hydrocarbon processing, chemical plants, and other industries. The focus is on preventing internal leakage when the valve is subjected to a standardized fire test. Key aspects of API 607 Scope: This standard applies to quarter-turn valves, including ball, plug, and butterfly valves, with soft seats made from elastomers or polymers. […]
