Kv values determined acc. to DIN EN 60534, flanges EN 1092. The Kv value data refers to control function 1 (NC) and the largest actuator for
each nominal size. The Kv values for other product configurations (e.g. other connections or body materials) may differ.

For max. operating pressures the pressure/temperature correlation must be observed (see table below).
All pressures are gauge pressures.
