Iris® valve UBXX

manualstainless steelaluminum

The Vortex® Iris Valve opens from and closes toward the center of its opening to create a gradual flow or restriction of materials. This design ensures an even discharge of materials and allows manual control over flow rates. The Iris Valve’s fabric sleeve and gradual closing action protect delicate and friable materials from degradation. When fully closed, the Iris Valve’s fabric sleeve is twisted to the point that it becomes a flat, tight barrier to hold back materials. Ideal application: Bulk bag unloaders and applications requiring manual control of gravity discharged, free-flowing dry bulk solid materials. Key Features Optional preset positions for quick adjustments in material flow rate Control ring constructed from stainless steel, for increased torque and added durability Optional replaceable wear liner reduces material contact with the sleeve to extend service life Sleeve is inexpensive and easily replaceable Flange options to matchup with equipment above the valve Optional double sleeve to better manage fine materials and dusts Control ring is precision-machined for quick, smooth actuation and to prevent binding and galling Optional double sleeve configuration Ideal for handling delicate or friable materials FDA-compliant materials of construction Conveyance Type Gravity flow only Materials Handled Non-abrasive to moderately abrasive powders, pellets and granules Standard Sizes 4 – 18 in | 100 – 455 mm Overall Height 2 in | 40 mm Weight 2 – 75 lb | 1 – 35 kg Connection Options Standard flange or tube stubs Ferrule-type fittings available by request Material Temperatures Up to 150°F | 65°C
