FutureFlow Diagram

Check valves permit flow in one direction only, and close automatically if flow reverses. They are entirely automatic in action, depending upon pressure and velocity of flow within the line to perform their functions of opening and closing.

Most Hattersley swing check valves can be installed in horizontal or vertical upward flow piping. Lift check valves must be used in horizontal lines only.
