High-Flow Diaphragm Valve Designed for Improved Flow Performance And Reduced Energy Consumption

GF Piping Systems has introduces the Type 514-519 high-flow diaphragm valve series for weir style valves.  The new valve features a 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 modified geometry provides linear flow and control characteristics designed to improve processing stability, resulting in reduced operating costs and more cost-effective media transport.  The self-draining feature can minimize dead space, improve hygiene and offer better resistance to crystallizing fluids. The valve design also eliminates traditional metal bolts required to hold the valve together. Instead, the top-works are threaded directly onto the body, eliminating the need to retorque 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 Series is available in PVC, CPVC, PP, PVDF and ABS body materials in sizes 1/2-2” (with larger sizes available in the 314-319 Series).  Diaphragms are available in EPDM, PTFE, FPM and NBR.  This material range covers nearly the entire spectrum of chemicals with which the diaphragm valves can come into contact.
