The spring seal/spring energized seal/varieseal is a high-performance seal that contains special springs in the U-type Teflon. The appropriate spring force is added to the system fluid pressure to push out the sealing lip (face). Gently press against the sealed metal surface to create a very good seal. The actuating effect of the spring can overcome the slight decentering of the metal mating surface as well as the wear of the sealing lip, while continuing to maintain the desired sealing performance.
PTFE spring energized rotating JTVM seal is used for rotating, reciprocating and static sealing occasions, no creeping operation, precise control and good scraping effect.
