Benchmark Report: A Comparison of Flow Coefficients of Furon®, GEMÜ® and Entegris Valves
December 10th, 2019
Three pneumatically actuated control valves with 2" union ends were tested to compare flow coefficients (Cv) in Ultrapure water (UPW). The valves tested were Gemü®, Entegris, and Furon® HGVM and configured as normally closed. Using ANSI/ISA–75.02.01–2008, “Control Valve Capacity Test Procedures” as a guideline, testing was conducted by a third-party semicondutor industry laboratory.
