BS1868 / API 6D Flange or Wafer Cast Stainless Steel Swing Check Valve

Check valve normally allows fluid (liquid or gas) to flow through it in only one direction.

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.

Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.
