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 seal material.

All pressures are gauge pressures. When the flow is over the seat (M), there may be the danger of water hammer with liquid media!
Kv values [m³/h]
Kv values determined acc. to DIN EN 60534.
The Kv values for other product configurations (e.g. other connections or body materials) may differ.
