Technical data

Working medium
Corrosive, inert, gaseous and liquid media which have no
negative impact on the physical and chemical properties of
the body and diaphragm material.

Data for extended temperature ranges on request. Please note that the ambient temperature and medium temperature generate a combined
temperature at the valve body which must not exceed the above values.

All pressures are gauge pressures. Operating pressure values were determined with static operating pressure applied on one side of a closed
valve. Sealing at the valve seat and atmospheric sealing is ensured for the given values. Information on operating pressures applied on both
sides and for high purity media on request.
Kv values determined acc.to DIN EN 60534 standard, inlet pressure 5 bar,∆p 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.
