Auto-Switch Cutting Tool

AST_01

Remote switching between
boring and cutting modes 

The innovative DeltaValve auto-switch coke cutting tool provides a high level of safety during de-coking operations by allowing the cutting tool to remain in the drum during switching of cutting and boring modes. Performance of the cutting nozzles are optimized for each pump pressure and drum diameter combination. For long term reliability, all internal mechanisms are isolated from exposure to cutting water and coke fines. Optional remote verification of cutting/boring mode is available.

The auto-switch cutting tool has successfully tested for cutting pressures up to 2000 PSI, and configurations up to 5000 PSI are currently in their final stages of testing.
