2 PagesPULP & PAPER U.S. Paper Mill Significantly Reduces Process Variability with Fisher TM Control-DiskTM Valves RESULTS • Process Variability Significantly Reduced Loop 1: from 8.0% to 3.0% Loop 2: from 3.5% to 1.6% After replacing two troublesome valves with Fisher TM Control-DiskTM valves, poor control was not an issue anymore. APPLICATION Vacuum control loops that remove water from pulp stock CUSTOMER A paper manufacturer in the U.S. A paper-producing machine at a U.S. paper manufacturer outputs more than 5,000 feet per minute on a 30-foot-wide roll. It uses a twin wire former to turn pulp stock, which is approximately 98% water, into paper. The former is the first place that water is removed from the pulp stock, using a vacuum control loop on the multi-foil shoes. Wa
