According to Vortex Valves, its Vortex Roller Gates are optimal for handling dry bulk material in gravity flow applications in which positive material shutoff and dust-tight sealing are required.

Vortex Roller GateAccording to Vortex Valves, its Vortex Roller Gates are optimal for handling dry bulk material in gravity flow applications in which positive material shutoff and dust-tight sealing are required. They additionally offer:

  • The flexibility to be applied to shut off or meter the flow of fine and moderately abrasive powders, and small to large granulars or pellets — or even sticky materials.
  • “Live-loaded” wear-compensating seals that prevent materials from escaping into the bonnet area of the gate and are easily replaced without removing the valve from the processing line.
  • Easily accessible nylon cam-adjustable rollers, which are critical to avoid material packing.
  • Horizontal or vertical valve orientation.
  • A wide selection of gate-positioning controls, position indication switches, flanges and actuation choices — including electric hydraulic, pneumatic, chainwheel and hand crank.
  • A variety of modifications to accommodate a range of temperatures, plus corrosive, humid or explosive environments.
  • Standard sizes from 6 to 36  inches(100 to 900 mm) that include an aluminum channel frame and stainless steel material contact.
  • Availability in a variety of configurations, including rectangular sizes and round inlet/outlet transitions for extra functionality.
  • An optional return pan to prevent material leakage into the atmosphere.
  • Ideal suitability for many dry material applications, such as mixing and blending, in the food, cement, chemical, plastics and textile industries.
