ABSTRACT:
A drill pipe tester valve includes a housing having a first end adapted to be connected to a well test string, which housing has a flow passage therethrough. A spherical valve member having a valve bore therethrough is disposed in the flow passage of the housing. Lugs are attached to the housing for engaging the spherical valve member and rotating the spherical valve member between open and closed positions as the spherical valve member is moved axially relative to the housing. A resilient coil compression spring is located above the spherical valve member, between the housing and the spherical valve member for automatically closing the spherical valve member when the well test string is statically positioned within a well, and for automatically opening the spherical valve member and allowing well fluid within the well to fill the well test string above the spherical valve member as the well test string is lowered into the well.
