8 March 2017 | PBEI Spherical Shutoff Valve Spherical shutoff valve is suitable for at- mospheric- and vacu- um-type mixer and dryer inlets and dis- charges. Valve slices t h r o u g h m a t e r i a l buildup and self-cleans with each cycle. Valve's sealing sur- faces aren't exposed to material flow, and there are no hidden areas for material buildup. Valve has no vane in the middle of the material stream, allowing smaller valves to be used with- out bridging concerns. Valve is specifically designed for bulk solids and slurries, providing a positive seal against material leakage and differential gas pressure. Roto-Disc, Erlanger, KY USA +1 513 871 2600 www.rotodisc.com Venturi Eductor Venturi eductor can be used to pneumatically convey high-tem- perature solids without moving parts. Eductor is designed for appli- cations involving fine, hot, or abra- sive materials, such as activated carbon, lime, coal, fly ash, sawdust, and soda ash. Eductor converts the pressure output from a blower into a negative pressure, so the unit can be placed below feeders, bins, and hoppers with no blowback or fugitive dust emissions. Fox Valve Development, Dover, NJ USA +1 973 328 1011 www.foxvalve.com Positive Seal Valve Positive seal valve (PSV) provides positive flow termi- nation in gravity flow and differential pressure applica- tions for specialty bulk pow- ders, granulated materials, aerated bulk solids, slurries, and liquids up to 14.9 psig (1 bar) pressures through the valve's body and across the sealing disc. Valve can have hy- draulic or pneumatic actuation, and the valve's tapered pivot- ing disc mates with a tapered seat on the inlet's throat to ensure positive sealing. Valve can be constructed from carbon steel, stainless steel, and other alloys.

Special Section: Valves Metering Valve Rotary cutoff metering valve provides accurate flow control of pulverized material using a V-notch rotor opening and a continuously modulat- ing actuator. Valve can be used for various applications, including silo loadout to trucks or railcars; precise flow control to other equipment with 4- to 20-milliamp signal feedback; and field conversion from rotary cutoff valve to ro- tary cutoff metering valve.
