BRAND: StafsjöCATEGORY: Knife Gate Valves

The Stafsjö high pressure knife gate valves model HP, HPT and HX are all strengthened to withstand high bi-directional process pressures. They are equipped with through-going “O” port gates and this ensures very safe and reliable shut-off of static and highly concentrated media. The excellent shut-off performance, together with excellent flow characteristics, makes them suitable for really demanding operating conditions with media as pulp (pulp concentration < 18%), liquor and highly concentrated slurry.

These valves represent three out of five valves in the Stafsjö product range with through-going gates. The HG represent the standard version while the HL is a slim line version of HG available in larger sizes and the HP is a high pressure version of HG. HPT is a high pressure version entirely made in Titanium and finally the HX is an extreme high pressure version for pressure rating PN20.

These valves are all modular in design and can easily be customised with gate, seats and gland packing according to media and requirements, as well for actuators and accessories.
