The Stafsjö XV bi-directional knife gate valve gives a secure and tight shut-off, independent of pressure direction. The valve design has good flow characteristics and can be used in applications with pulp, biomass and sludge, with the Polyurethane seated version extending its field of applications to include abrasive media.
The XV valve is available with the valve body fully lugged or semi lugged in stainless steel. The valve comes with the retainer ring system on both sides of the gate, which makes it independent of pressure direction and very easy to maintain. Even with its relatively low weight and very compact design the valve is able to cope with high bi-directional pressures.
