Type 514-519 High Flow Diaphragm Valve Series

The Type 514-519 High Flow Diaphragm Valve Series provides a break-through for weir style valves. The valve features an optimized, turbulence-free flow geometry that offers significantly increased flow rate performance and lower energy consumption. 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 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. Standard PVC, CPVC, PP, and ABS versions handle pressures up to 150 PSI while PVDF versions handle pressures up to 240 PSI.
