FIRE SAFE BALL VALVES TESTING
Features & Principles
Multitech makes fire-safe Ball valves are provided with cavity pressure relief arrangement in the ball, due to this feature rapid increase of pressure which may damage the internal mechanism is avoided.
In normal working conditions, the ball rests against two seats resulting in bubble-tight closer or no leakage found from the seating area of the Ball valve
In case of fire occurs or Ball, the valve is exposed to a temperature above the seat can withstand, ball seats from the ball become deformed or burn partially with resulting downstream secondary metal seat provides the leak-tight seal.
The fire safe test is performed with the standards API 607, API 6FA.
