A new body type for diaphragm valves from Burkert Fluid Control Systems offers advantages for hygienic environments.
Burkert Fluid Control Systems is showcasing a new body type for diaphragm valves at INTERPHEX 2016. Valves made with the new body type are aimed at applications completed in hygienic environments and are manufactured through hydroforming technology.
According to the company, the benefit of the new housings is that they are manufactured from stainless steel tube, such as that used in other plant or system lines. This match enables hygienic tube-to-tube welding of virtually identical materials, which ensures a uniformity of weld seams. Compared with cast bodies, neither cavities nor other defects occur in the manufacturing process, which means the risk of contamination is minimized.
The new body type lowers costs and reduces downtime. The housings also enable temperature control, reduce installation costs, and have shorter response times. The low mass allows users to profit from energy-savings by reducing the carbon dioxide footprint. The valves fulfill the ASME-BPE standard regarding dimensions and tolerances, as well as the European Hygienic Engineering and Design Group requirements regarding hygienic design. The tube valve bodies are available in the welding connection sizes ½, ¾, 1, 1½ and 2 inches with the Bürkert diaphragm valve types 2031 and 3233.
