Problem analysis

The force bypass diverts the applied force past the gasket once it exceeds a certain level, so that the gasket is pressed together with a defined force and the excess force applied, beyond that required for sealing, acts solely as a joining force between the metal components.

This therefore offers a number of benefits:

• Narrow sealing surfaces to achieve high contact pressure
• Protection against over-pressurisation
• Blow-out protection
• Minimising settlement effects
• Prevention of media abrasion
