Stafsjö’s HX knife gate valves are designed for high-pressure environments, alongside the HP and HPT models. These valves are robustly constructed to endure significant bi-directional pressures. Featuring through-going “O” port gates, the HX ensures a secure and reliable shut-off for both static and highly concentrated media. Their superior shut-off performance, combined with excellent flow characteristics, makes them ideal for demanding applications involving materials such as pulp (with a concentration of less than 18%), liquor, and highly concentrated slurry.
