30,000 psi high pressure/temperature seals are subsea valve replacements

Free Information on Trelleborg Sealing Solutions UK >>

Multi-Contact Turcon Variseal is introduced for high pressure / high temperature applications.

It is engineered to be 'immune to stick-slip' issues and to eliminate breakout concerns after long periods of inactivity, declares the manufacturer.

The new sealing products are developed to replace multiple chevron seals or V-stack type products in subsea valve stems that require a high-integrity sealing capability. It includes a series of single-acting spring-energized seals housed within a U-shaped Turcon PTFE-based seal profile.

Multi-Contact Turcon Variseal is designed to provide integrated redundancy to help extend seal flex life in high-pressure applications. With the addition of anti-extrusion devices, it can withstand up to 207 MPa and 30,000 psi.
