3-Way Circulation Valve

The DTI 3-Way Circulation Valve is specifically designed for bypassing CT Manipulation Tools during high rate circulation. The DTI 3-Way Circulation Valve allows the following circulation sequence:

• Initially all flow is through the Valve to the toolstring below only

• Circulating pressure is then increased to rupture up to 4 burst discs allowing high rate circulation to the annulus. At this point the first ball can be dropped to isolate the toolstring below the valve so that all flow is to the annulus only

• The second ball is dropped to return all flow through the valve to the toolstring below only

The DTI 3-Way Circulation Valve is commonly used for SSD shifting and circulating operations. A toolstring including the DTI 3-Way Circulation Valve and DTI Hydraulic Selective Shifting Tool can be used to open the SSD, pump high rate acid without circulating through the Shifting Tool, then close the SSD.

  • Alternate circulation to a manipulation tool, to the well, and then back to the manipulation tool
  • Reduce number of CT trips to complete manipulation and circulation operations
  • Activation pressures are fully adjustable
  • Large flow area during circulation to the annulus
  • Available in multiple sizes and material specifciations

DTI offer alternate sizes, materials and thread connections. Please contact us for more information.
