The check valve is the downhole safeguard, preventing back flow of well fluids into the tool string in the event of failure or damage. Maxwell Energy’s check valve utilizes a special twin flapper design with dual seals, which significantly increases safety during operation.

•Dual sealing system in each flapper assembly increases safety;

•Large I.D. design does not restrict the passage of balls or darts if required during operations;

•Made by special grade steel that can benefit from all the torque and tensile features, but more corrosion-resistable and wearable;

•Outer hexagon design enjoys easier maintenance and repair, improving the working efficiency;
