Rango de identificación de seguridad contra incendios de la válvula API 607

API 607 is a standard to defined fire test procedure for Quarter-turn valves and valves equipped with nonmetallic Seats. (For metal seated valves refer to API 6FA.) This standard covers the requirements and method for evaluating the performance of valves when they are exposed to defined fire conditions. In production facilities, valves are typically of a higher rating and the pressure source is not easily reduced when a fire is detected. Therefore, for all other valves, the test pressure during...
