Product Name: Teflon Spring Energized Ball Valve Seal

The Teflon Spring Energized Seal is located in the groove of the inner hole of the collar in the cylinder port or in the groove of the piston. After they are assembled in the assembly cylinder, the body of the seal ring under the action of the spring card in its lip, the two lips of the U-shaped ring are in close contact with the groove side and the sliding surface (the sealed surface) respectively, so as to seal the non-pressure or micro-pressure liquid fluid of the closed cavity of the cylinder body. When the pressure of the fluid increases, the lip of the seal ring bears the sum of the pressure of the fluid and the spring force, which is the self-sealing effect.

It is also significantly different from a lip seal such as a Y-shape. The Y-shaped ring uses the interference during assembly to generate the pre-tensioning force. This force is difficult to control. If the pre-tensioning force is weak or not, it is difficult to zero seal and micro-seal. However, due to the spring card effect, the flooding seal always has elastic force. On the lips. Therefore, when the fluid is not under pressure, the sealing lip still maintains a reliable sealing effect.
