Control Your Material Flow with Precision and Reliability

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

Vortex Pneumatic Gates

Isolate dry solids in pressure or vacuum conveying lines.

Vortex Orifice Gate

Orifice Gate for your process

The Vortex Orifice Gate uses a full-bore sliding opening for dry bulk solids. It is suitable for gravity flow and dilute-phase conveying, with pressure or vacuum suitability determined by size and configuration.

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

Also referred to as: Pneumatic conveying gates; Orifice slide valves; Pressure/vacuum slide gates.

Features to consider

Keep the bore clear

The open gate provides an unobstructed flow path.

Compensate for wear

Live-loaded hard polymer pressure plates maintain blade contact.

Access maintenance

A shimming system supports seal adjustment without removing the gate.

Configuration & selection

Duty
Dilute-phase pressure or vacuum conveying, and gravity flow.
Standard size range
2 to 16 in, with round openings.
Differential pressure
Up to 15 psig depending on gate size; confirm the selected configuration.
Material contact
304 or 316L stainless steel options.

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.

  • Line size, pressure, and vacuum
  • Required leakage performance
  • Actuator type and position feedback

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.
