Low-Leakage Rotary Valve for Pneumatic Conveying of Granular and Powder Products

Saving energy was the underlying factor for the development of a low-leakage rotary valve for pneumatic conveying of granular and powder products. The newly-developed rotor is designed with expanded tips at the end of the rotor blades. Wider vanes result in lower air leakage. In combination with the special rotor design, the number of rotor blades was increased. The valve is available for various differential pressure applications from 22 to 50 psi. The valve is designed for conveying capacities of 5000 to 200,000 lb/hr. The combination of wide end tips, increased number of vanes, and optimized venting provides a rotary valve with low air leakage. The valve is available in stainless steel and stainless steel/AL combination. Various sizes are available as is a quick-clean version.
