Vortex Iris Valves

Control a gentle, gravity-fed discharge.

Vortex Iris Valve

Iris Valve for your process

The Vortex Iris Valve uses a flexible sleeve that opens from the centre and twists closed. Manual adjustment allows progressive restriction of free-flowing dry materials, including delicate products.

Tell us what you handle, where the component fits, and what needs to improve.

Also referred to as: Iris diaphragm valves; Flexible sleeve valves; Bulk bag flow-control valves.

Features to consider

Adjust the flow

Change the sleeve opening to vary discharge.

Handle fragile product

The flexible sleeve and gradual closing action help limit damage.

Renew wear components

Replaceable sleeves and optional wear liners support maintenance.

Review the exact duty, material, temperature, connections, and control requirements with RTS before ordering. Published ranges cover a product family and vary by configuration.

Product photos

What to send RTS

A material name, a process sketch, and a description of the current problem are a useful starting point. Include throughput, bulk density, temperature, and operating conditions when available.

  • Discharge diameter and mounting
  • Bulk density and product fragility
  • Sleeve material and operator access

For replacements, send the existing model or serial number, opening dimensions, bolt pattern, available space, and photos.

Plan your application review

Can this replace an existing component?

Send the existing dimensions, connections, actuator details, and operating duty. RTS can review the installation and identify what needs to match before a replacement is selected.

How should we specify seals and materials?

Include abrasion, corrosion, cleaning, temperature, and product-contact requirements. Let us know any required documentation or hazardous-area classification.

Can we include the component in a larger process?

Share the upstream and downstream equipment and the intended operating sequence. RTS can help review how the component fits your conveying, batching, or loading arrangement.
