About HG
Stafsjö’s HG is a through-going high performance knife gate valve with superior flow characteristics, offering reliable bi-directional zero leakage shut-off on highly concentrated media and static media columns.
The HG knife gate valve is modular designed and can easily be customized in materials, with actuators and related automation accessories to different process conditions. It can operate on different media such as pulp stock up to 18% concentrations, slurry, liqour, ash and granulate. It is also widely used in junc traps, mostly as inlet valve with our RKO as discharge valve.
The HG has a rigid two-piece precision machined valve body with a high strength top works that provide an essential and precise gate alignment. As standard it is available with a valve body in stainless steel or nodular iron, but it can also be supplied in a range of high alloy materials such as Duplex and 254 SMO equivalent material.
The HG valve is one out of five of Stafsjö’s through-going knife gate valve models. The HP is a high pressure version of HG while the HL is a compact version. HPT is a high pressure version entirely made in Titanium and the HX is an extreme high pressure version.
