Dual Slurry Wafer Knife Gate Valve
From Dual Valves
Dual's Slurry Wafer Knife Gate Valve is built with a cast or fabricated steel body and features a heavy-duty stainless steel bade. Removable seats on either side of the blade, provide a Bi-directional seal and deflection cones are available in a wide range of polymers and hard FACW materials.
How the rubber inserts work
Matching rubber inserts are placed in the valve housing to seal against the gate when the valve is closed and seal against each other when the valve is open. This tight seal contains the high internal line pressure, precluding direct pressure against the secondary seal. Double seated design provides bi-directional flow and shut off.
