Coperion, Weingarten, Germany, will be presenting its re-engineered and optimised ZV rotary valve for pellets on Booth B19, Hall 14 at K 2016. Further developments have allowed throughput to be increased and noise emission significantly reduced. In addition, improvements to the rotary valve's housing have substantially lowered the gas leakage rate. Also the noise caused by leakage gas expansion, which is the main source of noise in high-pressure rotary valves (up to 3.5 bar differential pressure), has been reduced considerably by a new design of the expansion opening. 

 

For the first time the company will also be presenting the newly developed GAMMA-BEND NT deflector elbow, which prevents the formation of angel hair (see EBS News for week of 26 September). www.coperion.com
