Bürkert Fluid Control Systems presented a completely new body type for diaphragm valves that is particularly aimed at applications in hygienic environments at ACHMEA 2015. The bodies, manufactured using a patented manufacturing procedure – the hydroforming technology –satisfy the highest requirements imposed on materials and cleanability. With a lightweight, sustainable and hygienic design, the tube valve bodies are unique and compensate the weaknesses of forged and cast valve bodies.
With the introduction of the new tube valve body, Bürkert completes its product line in the diaphragm valve area and presents a high-performance alternative to forged and cast valve bodies. The new housings are manufactured from high-quality stainless steel tube, like the other plant or system lines. This enables hygienic tube-to-tube welding of virtually identical materials, through which a uniformly high quality of weld seams is ensured. Compared with cast bodies, in addition, neither cavities nor other defects occur in the manufacturing process, which means the risk of contamination is significantly minimised.
Target applications of the new tube valve body are in the demanding markets of pharmaceuticals, bio-pharmaceuticals, cosmetics, as well as the food and beverage industry. For the market introduction, the tube valve bodies are available in the welding connection sizes ½”, ¾”, 1″, 1½” and 2″ with the Bürkert diaphragm valve types 2031 and 3233.
