External face spring energized seals is the standard seal for axial (face) applications. It has a high spring loading, which gives excellent sealing integrity at low pressure and is available for both internal and external pressure.
The heavy helical spring in DVL makes it the best choice for vacuum, gas and low temperature flange sealing applications.
