In both in the chemicals processing industry and many other applications, valves very frequently come into contact with highly aggressive fluids. The advantages and disadvantages - or even the problems - of the valve materials used then become apparent very quickly. The safety, reliability and cost-efficiency of the valves used is decided, in particular, in the field of seal and gaskets. Fundamental properties, such as resistance to chemical attack, corrosion and temperature, and also per-meation rates, must be taken into account for all the materials used. These influencing factors become even more vital as temperatures and/or fluid concentrations increase. Mixtures of acids, and also cleaning proc-esses, have again and again proven to be extremely critical.
