CE CV Rupture Plug
The CE CV Rupture Plug allows the circulation of fluid through the CT tool under the normal operating conditions. By increasing the CT pressure to a predetermined value, the rupture plug will blow out, thereby opening a flow path from the tool string to the well. This valve is useful when a CT circulation flow path needs to be opened to the well below a tool requiring a drop ball, whilst leaving the tool string I.D. fully clear for other operations.
