The pressure rating (PN) depends on the diaphragm size.
Data for extended temperature ranges on request. Please note that the ambient temperature and media temper-
ature generate a combined temperature at the valve body which must not exceed the above values.

Kv values in m³/h
MG = diaphragm size
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 differ. 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 standard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and dur-
ation of use.
