Rounded Blade Gate

The Vortex® Rounded Blade Gate™ handles dry material in gravity flow applications where positive material shut-off and dust-tight sealing is required.

• Replaceable liners for added abrasion resistance
• True arc design for a more precise sealing surface that prevents wedging, lodging and spoilage
• Positive seal of materials/dust-tight seal across the gate and to atmosphere
• Replaceable bonnet seal for in-line maintenance
• Abrasion-resistant blade to prolong service life
• Removable access panel for in-line inspection and maintenance
• Rounded blade design and downward closure motion, for rapid actuation
• Dust-tight relative to the atmosphere
• Compatible with Vortex material flow control assemblies

Vortex Rounded Blade Gate vs. Alternatives

• Compared to conventional slide gates, the Vortex® Rounded Blade Gate™ actuates with much quicker speed and greater closing force. Generally speaking, the Rounded Blade Gate can actuate 2x faster than a conventional, pneumatically actuated slide gate. The purpose is to provide a quicker material shut-off. • When filling to specific batchweights, actuation limitations can impose on accuracy. The Rounded Blade Gate is compatible with Vortex’s many material flow control assemblies, to accommodate blade actuation into several intermediate positions. This allows total flow control for proper metering, which lends accuracy and repeatability to a manufacturing process. • Other curved blade gates have sealed bodies, which limits interior access. In order to perform inspection and/or maintenance, the gate must be removed from the process line so that its internal mechanisms can be accessed. This can lead to expensive and extensive production downtime. To allow in-line inspection and/or maintenance, the Rounded Blade Gate is designed with a removable access panel that can be removed using simple tools. This feature is especially beneficial in abrasive applications where frequent interior accessis required for wear part maintenance. The removable access panel feature significantly reduces downtime by accelerating the maintenance process. • Many conventional slide gates allow leakage of materials and dusts to atmosphere. The Rounded Blade Gate is dust-tight to atmosphere, meaning it is a self-contained unitspecifically designed to contain materials and dusts within the system. Therefore, the Rounded Blade Gate supports workplace safety initiatives, reduces product loss, and addresses atmospheric dust emissions and other potential environmental hazards.
