Diaphragm Valve Improves Flow Performance and Reduces Energy Consumption

The uniquely designed weir style valve features an optimized, turbulence-free flow geometry that offers increased flow rate performance and lower energy consumption. These features expand the valve’s suitability for applications where diaphragm valves were previously not considered due to flow restriction. The valve’s new flow geometry design provides Cv values double the traditional design with values ranging from 3.9 to 116.8, depending on size and end connection. The valve is available in PVC, CPVC, PP, PVDF, and ABS body materials in sizes 1/2- to 2-inch, with larger sizes available in the 314-319 Series. Diaphragms are available in EPDM, PTFE, FPM and NBR. This material range covers many chemicals with which the diaphragm valves can come into contact, optimizing process compatibility. Standard PVC, CPVC, PP, and ABS versions handle pressures up to 150 PSI while PVDF versions handle pressures up to 240 PSI. End connections include true union, spigot, flanged and zero static. Basic versions of the diaphragm valves are operated manually with a lockable hand wheel. A two-color position indicator shows the actual valve position. Suitable for extremely contaminated media, media containing solids, and high purity liquids for a variety of applications such as chemical process industry to microelectronics, water treatment, cooling and control.
