The Vortex HDP Slide Gate, offers the dry bulk solids industry a revolutionary new valve with expanded capabilities. This heavy duty slide gate:

• Handles non-abrasive to abrasive powders, granules, and pellets
• Isolates pressures up to 5 bars (75 psig) depending on size
• Will not leak to atmosphere or across valve
• Contains a displacement pocket that reduces / eliminates material packing as the blade closes
• Is maintenance friendly
• Is available in 4" through 16"

The HDP Slide Gate was developed to address these applications:

Patent pending, unique features include:

Self-adjusting blade and clevis At the end of the stroke, the blade rises vertically into the closed / sealed position. Seal adjustment and associated wear is greatly minimized. A displacement area at the end of the valve prevents material packing as the blade closes.

Self-adjusting bonnet seal cartridge As with the blade and clevis, the "live loaded" bonnet seal cartridge mirrors the perpendicular movement of the blade. Depending on valve accessibility, bonnet seals may be changed without taking the gate out of place.

"Tombstone" blade design and outlet transition The blade is unique in function and appearance. The tombstone shape allows for valve self-cleaning as well as enhanced sealing of material to the bonnet.

Industries: The Vortex HDP addresses material handling issues in traditional fine material applications, plastics, and foods. It further addresses applications for industries handling cement and other fine powders where dense phase or high aeration conditions are present.
