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.

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.
