Carefully selected materials for the longest lifetime and quality

Our carefully selected materials are used in different applications for different purposes. For example, we finalize our ceramics to very low surface roughness to make sure that fabric wear and power consumption is minimal.

Valmet is now able to supply complete offering of high-quality dewatering ceramics and two different types of polyethylene foils and covers. This means that you have access to complete through one source.
