Control Paper Grammage Weights Precisely Ball sector valve with precise positioning drive

摘要

The Griinewald company with headquarters in Hofolpe in the southern part of the Sauerland region has modernized its process control. Thanks to a new process control system and a new grammage weight control valve the company's throughput and paper quality are being further improved. Through the introduction of a highly accurate Sector Ball Valve with an internally mounted angle transducer and Stepper motor, a significant stabilisation of the process could be achieved together with improved quality at markedly higher throughputs.
