Al Kl O HOPPER SHAPE KNIFE GATE VALVE, TYPE CDatasheet Design features I BODY: Wafer style cast monoblock design with reinforced ribs in larger diameters for extra body strength. Internal cast gate wedges and guides allow for tighter shut-off. Special cast gate supports prevent seat from deflecting off the gate when valve is installed in the reverse position of the flow direction. Wide face to face and internal design with flushing corners avoid any build up of solids that would prevent valve from closing. Full port design for greater flow capacity and minimal pressure drop. Standard flush...
