The valves‘ technical design is based on media and application requirements.
This can lead to deviations from the general specifications shown on the data
sheet with regards to the design, sealing materials and characteristics.

actuation
If order or application specifications are incomplete or imprecise there exists
a risk of an incorrect technical design of the valve for the required application.
As a consequence, the physical and / or chemical properties of the materials or
seals used, may not be suitable for the intended application. To avoid hydraulic
shocks in pipelines, the flow velocities must be taken into account when
designing valves for liquids.
