Description

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. It is used to hold the tool open therefore it is possible to stab the valve while the fluid is flowing through the drill pipe. With the IBOP valve installed in the drill string, it allows you to strip in hole without mud flowing through the drill sting. The IBOP valve should not be used for shut the well in while tripping.We produce H2S resistance Inside Bop Valves, which adopt high quality import sulfur-resistance material.
