Fire Safe for Ball Valve per API 607
When the ball valve be used normally, it sealed by the Seat and Surface of the Ball, Seat Retainer sealed by the O-Ring and Valve’s Body, which are soft sealed, reliable sealing. When the Seat and O-Ring are damaged after be burnt, the Seat Retainer and Ball will be metal to metal sealed directly, on the same time, the Seat Retainer and Body will be sealed by expanded Graphite, which will effectively prevent both internal and external leakage of the valves, to achieve the Anti-Fire purpose.
All LYV Ball valves have Graphite Packing and Gasket to meet the Fire Safe Design per API 607, which can make sure the good quality and perfectly operation.
Anti-Static Device for Ball Valve
The friction between Ball and Stem with PTFE material, which generates static electricity and lights the combustibles and explosives that cause an accident. In case of this problem, an Static-Conduction Spring is set between the Stem and Ball, the Stem and Body, which can thus the static electricity is conducted to ground and make sure the pipeline system secured.
