(1) There is no standard for the size of flange gaskets in 2 Piece Threaded Ball Valve. The thickness of the gasket can refer to the relevant standards for pipeline flange gaskets, because the plates and strips used for gaskets are all of certain specifications and cannot be as thick as you want. (2) When using polytetrafluoroethylene as the gasket material, the structure must consider preventing cold flow.
