Coking Isolation Valve

Brand: ValvTechnologies

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 experience 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.
