Iris Valve

The Vortex Iris Valve provides gradual manual control of gravity-discharged, free-flowing dry bulk materials. Its fabric sleeve closes toward the center for even discharge, protects delicate and friable products from degradation and forms a tight barrier when fully closed. It is suited to bulk bag unloaders and similar applications.
