Rupture Disc Safety Circulating Valve For Drill Stem Testing Service
The Rupture Disk safety circulating valve is a part of DST tool string, the RD Safety Circulating Valve can be used as both a safety valve and circulating valve. The RD Safety Circulating Valve work as a safety valve when the annulus pressure reaches a predetermined value. At that pressure, the safety circulating valve isolates the workstring below the tool and establishes communication between the annulus and the workstring above the tool. The RD safety circulating valve converts into a circulating valve when the ball valve section is removed and attach a lower adapter called RD Circulating Valve. The valve can not be open when closed in downhole operation.
