>>Design solution


1. Energy storage lip seal structure

  • Energy SLS structure can make seal effort excellence, whatever medium direction, lip can seal flow with disc tightly.

  • Energy storage lip can compensate temperature or pressure is changing in big scope.

2. Special Anti-Fire design

  • PTFE insert Metal seal ring inside, PTFE as first seal ring in normally working.

  • When PTFE is burned, disc surface will touch metal seal ring, and metal ring will be backup seal ring.

  • In Normally working, metal seal ring don't touch disc surface, and valve torque will be control so exactly.
