Knife gate valve, type 7400

Type 7400 is a uni-directional knife gate valve and is a good choice when used for abrasive fluids such as pulp & paper, waste water, bio mass and mining slurries. Tightness in one direction will be secured with a resilient elastomer and metal seal. The valve can be delivered with rising or non-rising spindle. Actuation is provided with a hand wheel, chain wheel, gearbox, pneumatic- or with electrical actuation.
