  • Dual Activated Circulation Valve
Introduction
The Dual Activated Circulation Valve offers two methods of returning circulation of the tool string. In case that no circulation can be established, a certain pressure shall be built up inside the coiled tubing, and the burst disc will burst when the applied pressure is greater than the burst pressure so that the circulation is returned. However, the circulation can be established by using a drop ball. Pressure applied to the drop ball caused the shear pins to shear and the piston to move down allowing circulation via the side ports.
Features
• Different burst discs available.
• Activation pressure can be adjusted at surface.
