Double Flapper Check Valve

Double Flapper Check Valve

Double 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 pieces 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.

Description

The Double Flapper Check Valve is the standard check valve used in the standard check valve used in the majority of CT operations. It is mounted close to the top of the CT string, below the connector to provide a well control barrier inside the coiled tubing against the wellbore.
