MG = diaphragm size, Kv values in m³/h
Kv values determined in accordance with EN 60534, inlet pressure 5 bar, Δp 1 bar, with connection flange EN
1092 length EN 558 series 1 and soft elastomer diaphragm. The Kv values for other product configurations (e.g.
other diaphragm or body materials) may differ. In general, all diaphragms are subject to the influences of pres-
sure, temperature, the process and their tightening torques. Therefore the Kv values may exceed the tolerance
limits of the standard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and dur-
ation of use.
