Briefly Introduce:

The rupture disk (RD) safety circulating valve functions as both a safety valve and circulating valve, which is full opening, annulus pressure operated single shot safety circulating valve.

Structure Features

• The tool functions as a safety valve when the annulus pressure reaches a predetermined value. At that pressure, the valve isolates the workstring below the tool and establishes communication between the annulus and the workstring above the tool. This tool 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.

• RD Circulating valve is the same as RD Safety circulating valve except short of ball valve section, the annulus pressure made RD burst and the pressure goes into RD hole and push circulating mandrel forward, then open the circulating ports.
