Dewatering elements for board and paper machines

Increased production capacity and improved quality with proper initial drainage

Dewatering equipment beneath the forming fabric helps drain water from the stock and conduct it away into the whitewater system. We can offer you a comprehensive range of ceramics and polyethylene dewatering elements, and adjustable foils to suit all positions and OEM machine configurations.

Let us be your co-driver for success

Valmet solutions that combine parts and expert support will drive your production performances further. When you choose Valmet performance parts you are not just buying wear parts. You are also gaining greater availability, higher end-product quality and enhanced productivity.

With the combination of parts and expertise, we can together make a difference at every stage of your production process. We have increased production output and decreased total costs together by applying optimal performance parts to each position.

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.
