Dust-Tight Pneumatic Slide Gates

Automatic interim flow control in powder/bulk handling systems

Meyer Air-Operated Dust-Tight Slide Gates add an extra dimension of control to bulk material handling systems. Designed for use in free-flowing solids, granules or powder form, they can be installed to control flow from outlets of hoppers, silos, mixers, screw conveyors, truck train or ship load-out systems, etc.

Built of sturdy welded steel, Meyer dust-tight slide gate valves provide long life and dependable service. They are economical in cost and easily installed. Completely dust-tight when installed, they require no or minimum caulking.

Special construction materials such as stainless steel, aluminum, abrasion-resistant metals and special coatings are available.

System and gate-size related air cylinders open and shut the gates at a flip of a switch. Limit switches can be provided to indicate slide position.

Meyer pneumatic slide gate valves are available in sizes to fit standard square flange patterns of Meyer Airlock Feeders. Sizes to fit special requirements are also available. As the leading pneumatic slide gates manufacturers, we build all our equipment to ensure smooth operation and maintenance. Their self-cleaning capabilities mean less time spent on service and reduced downtime overall.
