The new, patent-pending wye line diverter is specifically engineered to handle dry bulk solids in pneumatic conveying systems with vacuum or positive pressures up to 15 PSIG. The line diverter, available in 2 -inch to 8-inch pipe or tube, can direct dry bulk material from one source to three destinations, or converge from three sources to one destination. The manufacturer utilizes precision laser cutting and bending technology to manufacture this leading-edge diverter valve. It provides a number of advantages over traditional flapper and rotating tunnel style diverters and eliminates trouble spots inherent in these conventional diverters. The wye line diverter provides superior sealing, low installation weight, fast “in-line” maintenance, and long-term, reliable service and provides positive shutoff of air and material improving process efficiency, minimizes cross-contamination, and eliminates material buildup beyond the closed port. The line diverter also offers a wide variety of modifications to accommodate high or low temperatures, corrosive, humid, and hazardous environments.
