Low-Leakage, Heavy-Duty Rotary Valves/Airlocks

Saving energy was the underlying factor for the development of a low-leakage rotary valve for pneumatic conveying of granular 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 valves are available for various differential pressure applications form 22 to 50 psi. The valves are 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 low air leakage. The valves are available in stainless steel and stainless steel/AL combination.
