Aggregate Gate

The Vortex® Aggregate Gate™ is designed to meet demanding applications handling material 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 valve body
• Displacement pocket prevents wedging and packing into an end seal
• Optional return pan redirects migrant materials in the bonnet area back into the material flow
• Constructed 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 & pinion gearing for quick, manual actuation
• Blade constructed from abrasion-resistant steel
• Replaceable abrasion-resistant liners for durability and prolonged service life

Blade and frame are made of 304 stainless steel. Rollers are 440 stainless steel and roller stud bolts are 304 or 18-8 stainless.

Modifications are made allowing 250°F (121°C) continuous to 300°F (149°C) intermittent service.

Modifications are made allowing 400°F (204°C) continuous to 450°F (232°C) intermittent service.

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

The dust seal will help to eliminate or reduce dusting to atmosphere. An example of an application the Enhanced Bonnet Seal option would be good for would be handling rocks with dust present. *Additional modifications available based on application.
