For a technically complex process such as the production and processing of plastic, the valves used must be just as technically complex - at the very least. Our melting valves are therefore always designed from the ground up for the specific application and extensively machined. This was also the case with this recent order, a DN 650 melting valve for a plastics plant in Spain.
Stable, precise and absolutely even
We put up to 10 hours of work into a single gate. After being shaped by flame cutting, our stainless steel gates are planed - for extra even surfaces. The CNC machine mills edges and holes. Finally, the entire gate is ground for a perfectly smooth surface.

Renovation of the pumping station for the water fountain
Abrasive mine slurry, sulfuric acid, temperatures of 220°C and high pressures: These W0 DN300 knife gate valves are working under extreme conditions. They were installed several years ago in a mine in Turkey. Body and gate are made of Super Duplex steel for higher resistance of the valves. The pneumatic cylinders have a fail-safe function: if power or compressed air should ever fail during operation, the valves close automatically to prevent damage.
Massive control gates for large masses of water
Our sluice gate type 2 is always used when especially large amounts of fluids must be shut off. The gate has a thickness of 12 mm and is additionally reinforced for a maximum head of water of 5.5 m. Two of these sluice gates will soon be installed in a wastewater treatment plant in Switzerland where they shut off the main inlet whenever necessary.
