Home > Industries > Refining > Visbreaking
During the visbreaking process, heavy coking of major equipment occurs frequently, thus requiring isolation valves to shutoff soundly and reliably for decoking operations.

MOGAS C-Series, with its expertly-engineered trim configuration, provides 100 percent reliability during the most severe operations and significantly reduces downtime when compared to conventional gate designs. For applications where heavy coking occurs, MOGAS also offers valves equipped with a continuous, intermittent purge system that removes troublesome coke buildup from seats and body cavities.
