Inside BOP/Stabbing Valves are designed to control or prevent a backflow condition when the kelly or top drive is disconnected from the drill pipe.
Description: Inside BOP/Stabbing Valves are designed to control or prevent a backflow condition when the kelly or top drive is disconnected from the drill pipe. Essentially a one-way check valve, they have a flush O.D. to permit them to be stripped through annular blowout preventers.
Features:
Releasing tools are supplied with the valve and they are used to hold the valve in the open position to allow it to be used as a stabbing valve. If a kick or backflow condition develops, the open valve can be easily stabbed and threaded into the drill pipe.
Unlocking the releasing tool allows the valve to close, preventing further back flow from the drill pipe. The releasing tool is then removed and normal circulation can be resumed through the valve to re-establish control of the well.
Sizes not listed, available on request.
