Rotary valve controls the flow of powders and granules

Coperion K-Tron

Coperion K-Tron

The Coperion ZRD Heavy-Duty Premium rotary valve (photo) is designed for industrial applications with pressure differentials up to 1.5 barg (21 psig), and temperatures to 100°C (212°F); higher-temperature versions are also available. The ZRD is used as a discharging and metering valve for conveying powders in granular and powdered form (with particle size smaller than 1 mm). Various materials of construction are available for the housing and endplates. These valve rotors are constructed of stainless steel DIN 1.4541 (AISI 321L). The valves handle a throughputs ranging from 0.1 to 300 ton/h. Thanks to its heavy-duty construction, the ZRD has an explosion-pressure shockproof rating of 10 barg, says the company. — Coperion K-Tron Salina, Inc., Salina, Kan.
