Swing-Away Back Pressure Check Valves for Container or Line Applications 6586D and A6586D


Designed to provide protection of a container opening when desired flow is always into the vessel. May also be used in the line applications where flow must be limited to one direction.

When used with the appropriate single check filler valve, the combination forms a double check filler valve suitable for use in filling of bulk storage tanks.

The swing-away check offers more efficient flow rates than conventional designs. It swivels open vertically to reduce pressure drop across the valve and improves flow rates.


  • Swing-away check design offers faster flow rates.
  • Heavy-duty construction for long service life.
