The Vortex Iris Valve offers a reliable valve to control the gravity discharge of free-flowing dry bulk material from bins, bulk bags, chutes and hoppers. A form-fitted, fabric sleeve provides a dust tight seal and a product barrier so material does not leak to atmosphere or come in contact with the valve’s actuating parts. Excellent valve for handling delicate or “friable” products.
Precision machined - Ensures that valve components actuate smoothly and flange connections match and seal properly.
Stainless control ring, metal locks and handles - Eliminates durability concerns of plastic control rings, plastic trigger locks and plastic handles |
