About Drop-In Check valves
Drop-In Check valves prevent return flow during a kick and are suitable   for most drilling situations in which return flow through the drill string is       a risk and normal operation requires the benefits of a full-bore sub. By preventing upward flow through the drill pipe and allowing fluid to be pumped downward to circulate the well, the valves provide the driller with the means to control the drill pipe pressures when required, significantly improving and simplifying well control.

When a blowout is about to happen,the thread connections of the kelly is screwed out immediately and a check valve is placed into the drill pipe and then pumped downward to the required place.Thus the blowout can be prevented.

When ordering please specify:

• • Smallest bore in drill string through which the check valve must pass.
  • Landing sub connection size and type.
  • Outside diameter of mating tool joints.
