Sealing blades - excellent wear and corrosion resistance secure long lifetime

Our blades have different geometries for each process: for surface sizing, for surface sizing and coating, and for high solids pigment coating. The design may also be optimized for your machine’s needs, to eliminate uncontrolled sealing blade bending, coat weight increases and unexplained splashing and misting.

In our newest product, Valmet Sealing Blade Bent (International patent pending), we have combined the excellent qualities of our traditional sealing blades with a pre-bent design. The design decreases the angle between the blade tip and the roll surface. It also increases the contact area in which sealing blade is touching the roll surface lowering the surface pressure between the tip area of the sealing blade and surface of the roll.

We offer fast and flexible deliveries – our sealing blades are packaged in cardboard boxes to prevent damages during transportation and for easy storage.


Rod shafts are available for old and new machines

Valmet’s rod shafts are designed to be fastened without tools ensuring quick replacement and reliable fastening. We have rod shafts always in stock in our local warehouses ensuring fast and reliable deliveries.

Customer case: Valmet Sealing Blade Bent minimizes unplanned shutdowns

A WFU machine running in Europe was using conventional sealing blades. Their lifetime was a maximum of 12 days, which meant frequent shutdowns for worn blade changes.

The blades were replaced by Valmet’s new pre-bent sealing blades. Their lifetime is minimum 21 days, which is the shut-down interval of the machine. Therefore, changing of the blade can be carried out during pre-planned shut-downs and no unplanned shutdowns are experienced due to worn blades.

Results from the customer case

Lifetime of the pre-bent sealing blade is minimum 21 days, which is the shutdown interval of the machine.

Changing the blade can be carried out during the pre-planned shutdowns.
