The Caledyne Completion Barrier Valve (CBV) is a down-hole barrier valve, which uses a ball to provide isolation between the upper and lower completion.
The CBV may be opened remotely by applying tubing pressure cycles, which actuate an opening mechanism at the top of the tool.
The CBV may be mechanically opened and closed with a shifting tool, both before and after it is cycled open.
Patent No. 2250338.
Forces due to pressure differentials across the ball do not affect the open/close mechanism or the remote opening module.
Smooth internal bore with a minimal number of locations for debris to collect.
Remote opening module can be replaced for different actuation modules or to vary the number of pressure cycles to open.
Internal equalizing mechanism across the ball allows for reduced loads to open the ball under high differential pressures
Trigger mechanism can be independently tested prior to assembling inside the valve.
- Formation isolation when installing the upper completion.
The Caledyne CBV is qualified to ISO 28781.For further details of our test programme please contact your nearest Caledyne representative.
