Roll-on Check Valve

Provide a Integrated Flap-type Chemical Injection Valve.

The tool is equipped with a double flapper check valve inside. During the process of injecting fluid into the well, the double flapper check valve is in an open state. After the fluid injection stops, the double flapper check valve can close automatically under the action of a torsion spring, achieving unidirectional flow within the pipe.

The double flapper check valve is entirely made of corrosion-resistant materials and can operate for a long time in complex fluids in the well.
