- 100% opening rate
As the plug is always closed when the gas pressure is released, steel infiltration into the gap is prevented which allows for 100% poening rate.
- Custom made
Gasflow / pressur configuration can be controlled by different settings on the pre tension of the bottom plate which means that the plug can be custom made for varius metallurgical conditions
- Increased lifetime
Since there is no steel infiltration in the gap after use, there is no need for a high openin pressur to spall of the infiltrated part of the plug, resulting in invreased lifetime.
- Unlimited gas flow
the costruction with a gap that grows with increased pressur makes it possible to achieve practically unlimited gas flow.
