Coking Isolation Valves
Increase your overall mean-time between repair/failure hours with ValvTechnologies’ coker valves
The delayed Coker process is a batch process, one of the most hostile environments in the refinery – due to the abrasive and erosive fouling properties of the coke by-product.The valves also expereince extreme thermal cycling. Valves are cycled frequently and failure can lead to a complete shutdown of a unit, resulting in large process and financial costs.
Improve up-time, avoid unscheduled downtime and lost production with ValvTechnologies’ coking solution.
- Reliability and longevity
- Operational and personal safety – reliability of tight isolation
- Most effective technological purging systems to prevent locking or coking up
- Low cost-of-ownership due to excellent run time and low cost of repair
