The High Flow Diaphragm Valve is a weir style valve, which features an optimized, turbulence-free flow geometry that offers significantly 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 modified geometry provides linear flow and control characteristics that improve processing stability, resulting in reduced operating costs and more cost-effective media transport. A self-draining feature minimizes dead space and achieves improved hygiene and better resistance to crystallizing fluids. The top-works are threaded directly onto the body, eliminating the need to re-torque the bolts due to thermal expansion. With its metal-free threaded bonnet connection, corrosive build-up is minimized in applications with highly aggressive media. The Diaphragm Valve is available in PVC, CPVC, PP, PVDF, and ABS body materials in sizes ½- to 2-inch (with larger sizes available in the 314-319 Series). Diaphragms are available in EPDM, PTFE, FPM and NBR.
