S. S. Iris Valve
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.
