Corrosion Resistance
If the unit is used for the intended purpose, its safety is not impaired by corrosion.
Sizing
The valve body must not be subjected to pulsating loads. Welds and flanges of the valve are designed
to withstand dynamic loading (bending and alternative stress).
The dimensional allowances for corrosion reflect the latest state of technology.
*) When used for its intended purpose.
Use CB... without springs for temperatures above 300 °C.
