Isolation Valves for Delayed Coker Service

2020 RefComm Global Presentation For refiners with delayed cokers, isolation valves are critical to safe and profitable unit operations. Historically, ball valve and wedge-plug valves have been utilized in many of these applications, but both designs are expensive to purchase, install, operate, and maintain. DeltaValve’s Delayed Coker Isolation Valve technology is unique. Modeled after the successful design of the world’s first fully automated bottom and top unheading valves, the single gate and dynamic seat design offers tight shut off as well as the lowest steam consumption in the industry. The high cycle internals are configured for shut-off as well as throttling applications and designed to operate from turnaround to turnaround minimizing downtime and maximizing reliability and refinery profitability. Additionally, the top entry design allows for in-line serviceability, making it possible for all internals to be replaced without removing the valve body from the line. DeltaValve’s presentation will focus on the advantages of its gate isolation valve technology as compared to ball and wedge-plug designs. DeltaValve’s Delayed Coker Isolation Valves are currently installed in several delayed cokers and operational feedback will be presented.
