Vortex Flex Tube Diverter vs. Alternatives
• Many alternative pneumatic diverters rely on soft rubber seals which are directly exposed to the material flow stream. These seals rapidly erode or tear away in service, which allows materials and dusts to leak into the opposite line(s) and to atmosphere. Seal damage can also cause actuation issues and several other maintenance concerns. The Vortex® Flex Tube Diverter™ addresses these issues by incorporating "live loaded" hard polymer pressure plate seals. Hard polymer provides greater wear resistance and longer service life than alternative sealing materials. The hard polymer seals are "live loaded" with compressed rubber backing to ensure even as the polymer experiences frictional wear from many actuations over time, the rubber load seals continuously force the polymer seals against the blade. The seals are also shielded from the material flow stream, to protect them from abrasion. This design maintains the diverter's positive seal of materials/dust-tight seal with infrequent maintenance intervention.
• Many alternative pneumatic diverters have open cavities where materials can wedge and prevent positive material shut-off. Wedging can also create seal wear and material degradation, and cause a valve to seize and bind. Wedged materials also create risk for cross-contamination and spoilage. To prevent wedging, the Flex Tube Diverter's sliding blade is designed to mechanically clear materials away from the sealing surfaces with each actuation. This ensures migrant materials are forced back out of the seals and are discharged into the process line, rather than packing in the seals and causing actuation issues.
• Many valves with sliding blades allow metal-on-metal sliding, which creates galling. This causes a valve to seize and bind, and can create foreign metal fragment contamination. The Flex Tube Diverter's hard polymer seals eliminate metal-on-metal contact to resolve each of these concerns.
• Alternative pneumatic diverters can pack and grind materials against the seals. This causes seal wear, material degradation and damaged product quality. To address these issues, the Flex Tube Diverter's "scissoring" action tapers off material flow as it shifts between lines. In keeping the pressure plate seals clear of materials, their service life is also extended.
• Many alternative pneumatic diverters have blade(s) and seals which are directly exposed to the material flow steam. This disrupts convey line pressures and obstructs material flow as they pass through the valve, which can cause line plugs and other maintenance concerns.To resolve these issues, the Flex Tube Diverter’s sliding blade is machined with an unobstructed, full-bore orifice that maintains convey line pressure and allows unrestricted material movement.
• Many alternative flexible hose diverters feature an exposed flexible hose. When installed outdoors, this subjects the flexible hose to its surrounding environment. Regarding operator safety, an exposed flexible hose also creates hazardous pinch points. To address these issues, the Flex Tube Diverter is designed with a housing that protects the flexible hose and encloses all moving parts.
