Swing Check valves are automatically actuated. They areused to prevent flow reversal in piping systems. They are suitable for service in the horizontal and the verticalorientation (flowup through valve). Swing check valves have low pressure drop characteristics and are best suited for moderate velocity applications. There is no tendency for the seating surfaces of swing check valves to gall or score, this is due to the fact that the disc meets the flatsent squarely and there is no rubbing upon contact.
