BRAND: StafsjöCATEGORY: Knife Gate Valves

The Stafsjö HL and HG knife gate valves excellent flow characteristics and gives a bi-directional tight sealing. They are equipped with through-going “O” port gates which provides a very safe and reliable shut-off on a wide range of harsh applications. This shut-off performance, along with its superior flow characteristics, makes them ideal for severe operating conditions with media such as pulp (pulp concentration <18%), liquor, rejects, powders, fly ash and highly concentrated slurry.

The HL and HG are two out of five Stafsjö valves in the product range with through-going gates. The HG represents 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.

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