Kv values determined acc.to DIN EN 60534 standard, inlet pressure 5 bar, Δp 1 bar, PVC-U valve body and soft
elastomer diaphragm.
The Kv values for other product configurations (e.g. other diaphragm or body materials) may dif-
fer. In general, all diaphragms are subject to the influences of pressure, temperature, the process
and their tightening torques. Therefore the Kv values may exceed the tolerance limits of the stand-
ard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and
duration of use.
