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.
