The Dual Flapper Check Valve provides a means of adding a uni-directional barrier to a BHA. The flappers provide a pressure-tight barrier in one direction, while enabling flow in the opposite direction.
The Dual Flapper Check Valve consists of a two-piece housing assembly that contains two removable flapper cartridges. The flappers are spring loaded in the closed position and are designed to open fully to give a large, uninterrupted bore through the tool.
The tool is easily redressed and the orientation of the flappers can be reversed depending on operational requirements.
