Maintain the seal
Live-loaded seals compensate for wear at the blade.
Vortex gates and valves are engineered to improve flow control, reduce leakage, and ensure consistent, reliable operation in bulk material handling systems.
Improve Flow | Reduce Leakage | Increase Reliability
Shut off gravity-fed solids without unnecessary leakage.

A slide gate for gravity-fed hoppers, bins, mixers, and conveyors. Vortex Roller Gates use a sliding blade supported by adjustable rollers and wear-compensating seals.
Tell us what you handle, where the component fits, and what needs to improve.
Also referred to as: Slide gates; Gravity slide valves; Hopper shut-off gates.
Live-loaded seals compensate for wear at the blade.
Adjustable rollers and replaceable bonnet seals support in-line maintenance.
Square and rectangular formats are available, with round transitions as an option.
Review the exact duty, material, temperature, connections, and control requirements with RTS before ordering. Published ranges cover a product family and vary by configuration.



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.
For replacements, send the existing model or serial number, opening dimensions, bolt pattern, available space, and photos.
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.
Include abrasion, corrosion, cleaning, temperature, and product-contact requirements. Let us know any required documentation or hazardous-area classification.
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.
