Operation under extreme conditions
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.
