TUSTIN, Calif. - GF Piping Systems' Type 514-519 High Flow Diaphragm Valve Series has been selected as one of the final nominees in Flow Control magazine's prestigious 2010 Innovation Awards program. Finalists were chosen based on the product's innovativeness for fluid handling technology solutions and then presented on Flow Control's web site for readers to vote on. Winners will be announced in Flow Control's December issue.
GF Piping Systems' uniquely designed 514-519 valve provides a true break-through for weir style valves. The new valve 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 innovative valve design also does away with traditional metal bolts required to hold the valve together. Instead, 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. This material range covers practically the entire spectrum of 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 handwheel for protection.
GF Piping Systems' New Diaphragm Valve Series Offers Improved Flow Performance and Reduced Energy Consumption against unwanted use. An optional self-adjusting electrical feedback unit can be quickly retrofitted, enabling automatic control, piping system regulation and reliable process monitoring.
Additional design features include rounded contours with smooth transitions and radii, which provide less abrasion and noise emission. Color coding on the housing nut and on the housing itself allow easy indication of pressure rating and diaphragm material. A two-color position indicator, which is clearly visible from a distance, shows the actual valve position.
The new valve family can be completely automated with GF Piping Systems' Pneumatic Actuators DIASTAR 10 (150 PSI) and DIASTAR 16 (240 PSI). Modular design allows easy field installation of the actuator to a manual valve as well as position feedback switches and other accessories.
The new valve series is 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.
