Volume metering controls from Salina Vortex Corp., Salina, Kansas, U.S., a manufacturer of slide gates and diverter valves for handling dry bulk materials, allow variable positioning of the gate blade, providing maximum flow through a fully open fate with the option to vary the position of the blade on the opening or closing stroke.
Large volume air controls provide a quick blade speed and high cycle service. Gate blade positioning is repeatable to within plus or minus 1/16-inch of its set point and is not affected by materials handled or gate wear conditions, allowing for accurate material weights.
Preset variable positions will not float past set points as with traditional bulk and dribble feed controls. Each position is 100% adjustable over the stroke of the gate and can be easily changed in a matter of minutes.
