Coking Valves
Decrease unscheduled downtime and possible production losses 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 properties of the coke by-product – and is crucial to a refinery’s profitability. Valves are cycled frequently and failure can lead to a complete shutdown of a unit, resulting in large process and financial costs. Optimizing valve life-cycle is critical to operational efficiency: ValvTechnologies has the best solutions to meet your coking requirements.
FAQs – Coking Valves
What makes coking valves critical in delayed coker units?
Coking valves operate in one of refinery’s most hostile environments: high temperatures, abrasive coke, thermal cycling, and frequent operation. Valve failure can result in full unit shutdowns and costly downtime.
What enables resistance to thermal cycling and coke buildup?
- Integral seats manage extreme thermal cycling.
- Continuous steam purging/flushing systems prevent coke residue from accumulating, while minimizing steam usage.
How is stem integrity ensured under high stress in ValvTechnologies coker valve solutions?
The stem is blowout-proof, supported by an integral body shoulder with no external pins or collars, thus enhancing mechanical safety.
What installation configurations and features are available for coking valves?
- Full-bore design for unimpeded flow.
- Bi-directional sealing for flexible service.
- Flanged end connections as standard.
