Dual Action Ball Valve 5" 15000psi Drill Stem Test Tools

Drill Stem Testing(DST) Tools Dual Action Ball Valve, Rupture Disk operated 5"OD x 15000 PSI, 400F, 3 1/2" IF or 3 7/8" CAS

Introudction 

The Dual Action ball Valve is the annular Rupture disc controlled ball valve type tools, also called RD DAV, can be used as a tester valve or a safety valve to close the well under emergency condition. The RD-DAV can be run in hole in either the open or closed position, the tool 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. The Dual cycle configuration provides downhole tester valve with one shut in cycle for a pressure build up, and the ability to re-open for an additional flow period or well kill procedures.

On the other hand, to be as the downhole tester valve to crease well flow, the data collect can only be referenced, normally to get accurate data or parameters, third open and third close will be very necessary.

There are two rupture discs installed, one is for lower pressure Rupture disc and another is for higher pressure Rupture disc that selected base on filed application or testing procedures, the selection of rupture disc will be important to operate the tool.

Features and Benefits
