• Swing Check Valves used to prevent the reversal flow through pipe lines. These valves are used only for upward or horizontal flow. It offers low resistance to flow and are particular suited to low velocity services.

SWING TYPE DISC:

• Disc is opened by line velocity and the resultant pressure. When the flow stops, the disc is closed by gravity. Seating load and resultant 

  tightness is depends up on the back pressure.

[A] Out side lever and counter weight design:

• The objects of the lever and weight is either to balance the disc or give it added weight. Unbalancing the disc the valve will open with a minimum    pressure. When the disc is weighted the valve will be sensitive to reversal of flow. 

[B] Dashpot Arrangement:

• Incase of intermittent use or in presence of thrusts, dashpot design is highly recommended.

• In such instance the dashpot design gradually causes the opening and closing of disc preventing, therefore dangerous shocks.
