DST Tools Dual Action Ball Valve For Oil Well Donwhole Testing
The Dual Action Ball Valve is the part of DST tool string, the dual action ball valve is controlled by the annular Rupture disc,also called rupture disc dual action valve or RD DAV. The dual action ball valve can be used as a tester valve or a safety valve to close the well under emergency condition.
The rupture disc dual action ball valve can be run in cased hole in either the open position or closed position, the ball valve can be operated by twice, so called as Dual action or dual shot valve. In the single cycle configuration, the RD-DAV can be used as a tubing string pressure test valve, or as a safety shut in valve in wells where a secondary downhole barrier is required.
