Coking Isolation Valves

Sizes : 1 – 36” | Pressure Classes : ASME / ANSI Class 300 – 2500

General Details

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
