The DTI Coiled Tubing Twin Flapper Check Valve provides a dual barrier within the coiled tubing tool string as safety critical protection against fluid back flow. It is robust, reliable, easy to redress and rated to 10,000PSI.
The flappers are mounted integrally into the body of the tool to maximise flow area whilst providing a simple efficient and cost effective method of forming a well barrier.
The flappers have metal seating with no elastomers present and are capable of sealing at very high pressures and temperatures.
