Descriptions of IBOP Working pressure 70 (35) (Mpa) OAL mm 711 (28) (inch):


The IBOP is a non-return valve (check valve), also called Gray Valve or BVR, is a back pressure valve used in the drill string to prevent the well from flowing uncontrollably up the drill string. When the blowout occurs during lifting operations, the IBOP have many advantages in situation such as, high pressure rating, reliable seal, easy application and operation.

When the drill tool is lifted out of the hole, a blowout could happen due to suction. In event of a blowout, the open position of the IBOP valve allows backflow, easing the installation process. Upon successful installation, the valve can be promptly closed with a relief rod to prevent further backflow. Fluid can then be pumped in from the surface to discharge the IBOP and drill string. The purpose of blowout prevention can be achieved by the following generic steps: discharging the relief sub; regulation of fluid; commence pump circulation.
