Abstract: The Montgomery Soft Stroke One Way Valve is designed to open and close more than four million times a year, as floats in the ocean go up and down with swells to compress water to make electricity. The valve is preferably round with vanes that open and close. The vanes are spaced around the valve body much like the segments of a grapefruit cut in half. Each segment is made with 60% surface on one side and 40% surface on the other side of a sealed bearing pivot rod. The 60% side of the vane will open with the flow of water and the 40% side will open against the flow, that will lessen the striking force of the vane. The striking surface of each vane and body will be coated with durable material to reduce wear.
