DeltaValve® Coke Drum Unheading System
First fully automated, inherently safe system

Curtiss-Wright’s DeltaValve provides the first fully automated, inherently safe system for releasing residual coke from large pressurized drums during crude oil processing.  By creating a completely sealed connection from the bottom of the coke drum down through the discharge chute, the DeltaValve completely isolates personnel and equipment from exposure to heat, water and steam. 

Significant advantages include:

• Unsurpassed safety record
• Increased cycle times and throughput
• Minimized operation and maintenance costs – currently five-year operating performance with no downtime
• Enabling refiners to process extra heavy, sour grades of crude oil, which are less expensive – vast reserves in regions such as the Orinoco Belt in Venezuela and the Canadian oil sands are just beginning to be tapped

The unparalleled safety and economic advantages of this innovative, patented design has captured nearly 34% of the global market since its introduction in 2001.
