SLFKnife Gate Valve

Stafsjö’s HPT knife gate valves are engineered specifically for high-pressure environments. This series, along with the HP and HX models, is designed to withstand significant bi-directional pressures. The valves feature through-going “O” port gates that ensure a safe and reliable shut-off for both static and highly concentrated media. Their excellent shut-off performance, combined with superior flow characteristics, makes the HPT valves ideal for demanding operating conditions involving materials such as pulp (with a concentration of less than 18%), liquor, and highly concentrated slurry. ​
