MG = diaphragm size, Kv values in m³/h
Kv values determined in accordance with DIN EN 60534, inlet pressure 5 bar, Δp 1 bar, with connection flange
EN 1092 length EN 558 series 1 (or threaded socket DIN ISO 228 for body material GGG40.3) 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 pressure, temperature, the process and their tighten-
ing 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.
