The double disc arrangement with the internal wedge mechanism ensures
- No jamming of the discs, not even under most stringent operating conditions. When actuating the non-selflocking wedges the discs collapse and are free to be moved.
- Tightness and flexibility given by pressing of the discs via central ball between the internal wedges.
- Minimum wear due to short travel contacts on the sealing seats.
- Double Block and Purge or Bleed
- Under low differential pressure seat surfaces free of wear due to axial pressing in closed position.
Operating conditions
- High temperature
- Temperature operational variation
- Temperature operational differences
- High differential pressure
- Line Stresses
- High frequency of operating
- Quick closing and opening time
Typical application

- Cyclic Powerformer Units
- Ethylene plants
- Fluidized catalytic cracking units (FCCU)
- Coal gasification plants
- Cupola furnace units
- Zinc melting furnaces
- Waste heat boilers
