The BT Dual Flapper Check Valve provides a means of adding a unidirectional barrier to a Bottom Hole Assembly. The Flappers provide a pressure tight barrier in one direction but enable flow in the opposite direction.

The Check Valve consists of a three piece Housing Assembly which contains two removable Flapper Cartridges. The Flapper Cartridges are spring loaded in the closed position and are designed to open fully to give a large, uninterrupted bore through the Tool. Each Check Valve Housing Sub contains two Flapper Cartridges for 100% back up.

The Tool is easily redressed with o-rings and the orientation of the Flappers can typically be reversed depending on operational requirements.

The Connections on the Subs are manufactured to suit BHA requirements.
