Knife Gate Valve for High Pressure Applications
Stafsjö’s high pressure knife gate valves HP, HPT and HX are all strenthened to withstand high bi-directional pressures. They are equipped with through-going “O” port gates and this secure a really safe and reliable shut-off of static and highly concentrated media. This shut-off performance, along with its excellent flow characteristics, makes them suitable for really demanding operating conditions with media as pulp (pulp concentration < 18%), liqour and highly concentrated slurry.
