    I have never heard one called a flow check before. A swing check has a door on a hinge that swings out of the way when water flows past it. Then it can close with a bang when the water stops. A line check has a poppet which is spring loaded so it can't bang closed. The swing check is usually used for sewage applications where there is minimal pressure. The line check is used on pressure systems.

      A flow check is used on hydronic heat to prevent flow in a zone not calling for heat. There is weight to stop the flow no spring or flapper
