Swing Check Valves, also called Clack Valves , Non Return Flap Valves or Plate Check Valves are what most people think of when (if) they think Non Return Valve. 

A circular door is hinged at the top and swings up to allow flow.  This design is suitable for mounting horizontally or vertically with upward flow - they are not suitable for vertical downward forward flow unless fitted with a counterweight.

We have a simple low cost version that clamps between flanges together with more conventional designs where the disc swings within the body.
