Coking Isolation 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 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.
