Gravel Pack Valves

Tendeka developed the FloCheck Injection GP Valve which provides injection capability with both ICD and AICD completions.  The valve is designed for chemical stimulation injection through screens, and to fully shut-off under production condition.

During injection, the valve requires a positive injection pressure differential, or a pre-set pressure, to activate and open to allow fluid to pass through.  This opening pressure can be controlled by designing the appropriate spring force to match the activation pressure for injection.

During production, the bypass valve will remain closed due to a spring force applied on the disk to keep it shut off and the pressure drop across the ICD.
