High Performance WB14E
Stafsjö’s WB14E knife gate valve is a high performance shut-off valve with superior flow characteristics, offering bi-directional zero leakage shut-off up to 150 psi/10 bar. It is suitable for media such as pulp stock, chemicals, sludge, bio mass, slurry and water. The fully lugged body design is suitable for dead-end services.
The WB14E is supplied with stainless steel wetted parts including the fully lugged valve body, highly polished gate and gland. Stafsjö’s gland box system with TwinPack braids and extra PTFE scrapers ensures that no media reaches the surrounding environment. A smooth cycling and a tight shut-off independent of valve position is achieved by the high strength top works that provide an essential alignment for the gate. It utilizes stainless steel tie rods encapsulated inside the structural beams.
Stafsjö’s fully modular concept is also applied on this WB14E which makes it easy to equip with manual as well as automatic actuators and related automation accessories. The valve is also available with mechanical lock out.
