The Vortex Quantum Series Orifice Gate valve offers significant advantages over traditional knife gates and butterfly valves.  Other gate valves, knife gates, slide gates, and butterfly valves rely on soft rubber seals that erode away or tear when handling dry bulk material.  The Vortex Quantum Series Orifice Gate valve eliminates these problems by using “live loaded,” hard polymer seals.


Material wedging
- Knife gates and butterfly valves with round end blades commonly allow wedging of dry material – preventing positive air and material shut off.  The blade jams and packs material against the seals, quickly abrading the seals.  The patented design of the Orifice Gate valve clears material away from the sealing areas to allow positive gate valve closure and minimal seal wear.

Valve cleanliness - Other knife gates contain retention ledges and areas where materials can become trapped.  This creates spoilage of material and blade actuation problems.  The Vortex Orifice Gate valve is a full-ported valve, with no ledges.

Material flow - Butterfly valves utilize a disc that reduces the material flow area.  Certain material has a tendency to pack and bridge around the disc.  The Vortex Orifice Gate valve offers unrestricted material flow for enhanced system performance.

Many choices - Vortex slide gate valves offer customers a choice of sizes, mounting options, actuators, and materials of construction.  These choices help create the proper valve for the right application.
Hard polymer seals - Other gate valves, knife gates, slide gates, and butterfly valves rely on soft rubber seals that erode away or tear when handling dry bulk material.  The Vortex Orifice Gate valve eliminates these problems by using “live loaded,” hard polymer seals.

Applications:
The patent pending Vortex Quantum Series Orifice Slide Gate is versatile and well-suited to many different dry material handling applications:

  • Gravity flow or dilute phase pneumatic conveying (pressure or vacuum)
  • Handles non abrasive to moderately abrasive powders, granulars or pellets
  • Horizontal or vertical valve orientation
  • Open / closed or volume metering of material
  • Modifications available for a variety of environments

Key industries served: Bakery, Chemical, Food, Milling, Mineral, Paint, Pet Food, Pharmaceutical, Plastic, Rubber, Soap, Textile, Tobacco.
