We’re here to change your mind and get you as excited about these innovative valves as we, their inventors, are about them.
From fine powders to heavy particle output like ceramics and metal, Mitsumi iris valves with their unique rope closing design can handle jobs you’d never believe a fabric choke valve could.
Mitsumi Iris Valves are designed for medium duty and regular operation in bulk solids processing. They can be used both in-line for flow control and for discharge functions. They are suitable for processing a wide range of bulk solids, from heavy particles to fine powders. Including sanitary applications.
Mitsumi Iris Valves are the result of precision engineering. Flexible sleeving, high-strength ropes, and durable metal casings come together to provide superior control over a wide range of bulk solids processing. The flexible sleeve is the only material that comes in contact with your product in-line so there’s no worry about metal flakes contaminating your output.
The sleeve is set in a flange on the valve casing with choke ropes running in parallel between the two rings of the casing.
Turning the handle just 90° rotates all ropes simultaneously so they close the sleeve and form a complete seal.
Different models offer unrestricted flow control, step set partial flow control, or automated control.
