The Ball Check Valve is a standard coiled tubing string component. Its use in a tool string, provides a means of preventing the back flow of fluids into the coiled tubing, in the event of failure or damage to the surface equipment.

Ball Check Valves are used when devices such as balls and darts do not need to pass through the valve. In the event of a ball or dart needing to be dropped, a Flapper Valve must be used.
