Saving energy was a major requirement that led to the development of a low-leakage rotary valve for pneumatic conveying of granular products. This valve has a newly-developed rotor designed with expanded rotor blade tips and wider vanes for lower air leakage, and an increased number of rotor blades. The valve is available for a variety of differential pressure applications from 22 to 50 psi and conveying capacities of 5000 to 200,000 lb/hr. The combination of wide tip ends, increased number of vanes, and optimized venting provides a rotary valve with low air leakage. The valve is available in stainless steel and a stainless steel/aluminum combination.
