Delayed Coking Bottom Unheading: Compact Design
Fully automated, compact double-disc gate valve ensuring safe, reliable bottom unheading in delayed cokers.
Reduces steam consumption and energy waste, enhancing environmental safety and efficiency.
True double block and purge functionality ensures superior isolation and minimal emissions.
Fully automated design enables remote operation, eliminating the need for an operator on deck.
The Delayed Coking Bottom Unheading Compact Design is a fully automated valve system based on IMI’s proven double-disc gate valve technology. Designed for reliability, safety, and efficiency in delayed coking applications, this compact solution reduces weight, steam consumption, and erosion while maintaining robust performance. Featuring true double block and purge functionality with two independent discs, it ensures precise sealing and minimal maintenance. The guided carrier prevents coke fines from entering the valve body, eliminating the need for cooling water. Actuator redundancy and remote operation capabilities enhance operational safety and uptime, making it a top-tier choice for modern refining applications.
