17_3_1The CVI dual plate check valve design conforms to API594 and API6D. And it is generally stronger, lighter, smaller, more efficient and less expensive than conventional swing check valves. It has about 25% the face to face dimension and 15% to 20% the weight of a swing check valve and making them less expensive than a swing check valve.
