Valvulas - Model T300 -Bidirectional Slurry Knife Gate Valve
The Model 300 is a Bidirectional cutting wafer knife gate valve where the knife moves completely through the inner part of the body cutting the flow. The knife has a central round-shaped blade which, when opened, aligns with the bore of the valve hole, forming a clean straight-through path. Therefore, the fluid flows without any obstacle. Designed for fluids with suspended solids, with a maximum concentration of 20%. Internal guides for smooth movements. High temperature design available with internal graphite sealings.
