Drop Ball Circulation Valve (Normally Open)

The DTI NOCV allows the circulation of fluid from the CT tool string to the well under normal operating conditions. By dropping a ball, this circulation path is closed off and fluid is diverted through the tool string. This valve is useful when a deliberate applied pressure needs to be delivered to the CT work string.
