50High pressure ball valve seat seal
The spring energized seal can select different spring forms and sealing lip designs according to the applications such as dynamic, static, internal and external pressure, resulting in impassable sealing force and compression deformation. The spring force will affect the performance, friction and wear performance of the jacket. The compressible stroke determines the compensation ability of the jacket for the wear of the sealing lip and the dimensional tolerance variation of the sealing groove.
Customized products can be developed according to customers' needs.
