Condition:
After the check valve in flow direction the pipe-DN must correspond to the check valve-DN. Recommendation for vertical type: DELTA.
When vertically installed (=0°) resp. (up to 60° angle) ball ceck valves close automatically, because ball is guided in the centre of the bore. When horizontally installed (=90°) resp. (up to 30°) the valves close automatically if the back flow related water is 1,5 – 2,5 m/sec.
