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