Iris Valve

Gravity Flow Conveying

The patented Vortex Iris Valve is designed specifically to handle dry bulk solids in gravity discharge of free-flowing material from bins, bulk bags, chutes, and hoppers.  The Vortex Iris Valve is designed with stainless steel control rings, metal handle and trigger lock, and nylon shim for durability and smooth actuation.  A form fitted fabric sleeve provides a dust tight seal and product barrier, which prevents material leakage into the atmosphere.

  • Ideal for bulk bag unloading
  • Smooth actuation with no binding or galling
  • Unrestricted flow of material
  • Fabric sleeve prevents material degradation
  • Stainless steel control ring
  • Standard sizes: 4″ – 18″
