The ZRD rotary valve (photo), designed for discharging and metering powders and granular solids during conveying, is the newest member of the company’s Aerolock family of rotary valves. It is specially designed for food, mineral, plastics and chemical applications. The valve is engineered for heavy-duty industrial service with pressure differentials up to 21 psig (1.5 barg) and temperatures up to 212°F (100°C), and higher-temperature options are available. An extensive range of sizes is available, with large throughputs from 500 to 400,000 lb/h). The valves have a pressure-surge-proof (pressure-shock) rating up to 145 psig (10 barg), and are suitable for isolation according to NFPA standards (for select sizes up to 12 in.). — Coperion K-Tron, Salina, Kan.
