0 — 16 bar
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.
Since the high operating pressure may reduce the service life of the diaphragm, please adapt the
maintenance intervals accordingly.

Kv values in m³/h
Kv values determined in accordance with DIN EN 60534 standard, inlet pressure 5 bar, Δp 1 bar, stainless steel
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 stand-
ard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and dur-
ation of use.
