DeltaValve’s extensive experience in designing and building engineered severe-service industrial valves and equipment for delayed coking has made us a world-recognized industry leader. In 2001, DeltaValve designed, engineered, and installed the world’s first fully automated, fully enclosed coke drum unheading valve at the Chevron refinery in Salt Lake City, Utah. This new valve technology revolutionized coke drum unheading by replacing traditionally unsafe and unreliable manual or semi-automated unheading equipment, with a fully automated system. The result has been a safer working environment, reduced downtime, and increased productivity.

DeltaValve continues to develop new and innovative products to address some of the most challenging applications within delayed coking. To date, the company has been awarded over 110 domestic and international patents for its revolutionary designs.
