Aggregate Gate

The Vortex® Aggregate Gate™ is designed to handle demanding applications involving materials such as sand, gravel, whole grains, and coal.

• Seals are protected by a series of deflectors and retainers to reduce wear and extend service life
• Removable bonnet cover for easy inspection of the valve body
• The displacement pocket prevents wedging and packing into an end seal
• An optional return chute redirects material that has migrated into the hood area back into the material flow
• Made from specialized metals and polymers for application-specific durability and abrasion resistance
• Modifications allow the gate to be used in higher-temperature applications up to 550°F | 290°C
• Optional side-mounted handwheel with rack-and-pinion gearing for quick, manual operation
• Blade made of abrasion-resistant steel
• Replaceable, abrasion-resistant liners for durability and a longer service life

The blade and frame are made of 304 stainless steel. The rollers are made of 440 stainless steel, and the roller stud bolts are made of 304 or 18-8 stainless steel.

Modifications have been made to allow for continuous operation at 250°F (121°C) and intermittent operation at 300°F (149°C).

Modifications have been made to allow for continuous operation at 400°F (204°C) and intermittent operation at 450°F (232°C).

The slide blade is made of AR plate for handling more abrasive materials.

The dust seal will help eliminate or reduce dust emissions into the atmosphere. An example of an application where the Enhanced Bonnet Seal option would be useful is handling rocks in dusty conditions. *Additional modifications are available depending on the application.
