Leak Diagram

Leak diagram

In the range of turn 0 - 3 the diaphragm does not touch the valve seat. Due to physical reasons, control between 10 E-9 und 10 E-10 is not possible, if used at room temperature (red range in the diagram). In this case the valve is tight approx at turn 9 to 10. Control in this range is possible if the valve is heated.

Maximum throughput is 60 mbar.l/s
