Characteristics
The Valvograph V48Z graphite sealing ring gaskets for valves offer high thermal and chemical resistance, making them virtually universal and suitable for all industrial applications. The density of the molded product ranges from 1.40 to 1.70 g/cm³, but limitations may occur depending on the size of the graphite sealing ring.
Applications
Valvograph V48Z seals are available both as individual components for general sealing applications and as pre-packaged sets for valves. Thanks to their high thermal and chemical resistance, these gaskets are suitable for use across a wide range of industrial sectors. Valvograph V48Z graphite rings can be used to seal all fluids except oxidizing ones.
