Application

Check valves are installed in a pipeline to permit flow of air in one direction only.
Less than 1/2 psi pressure is required to open the valve. The valve is spring loaded to close when no pressure differential exists.
Therefore, it may be mounted in any position.
The body and cap are made of anodized die cast aluminum. A stainless steel valve, plated spring and Buna N Seal also contribute to trouble free service.
