The perfect solution for abrasive wear The state-of-theart special ball valves, which ATEC manufactures and markets itself, feature a T-bore, which allows a flexible 3-way redirection of the material flow. New, metal-sealed 3-way ball valves with minimised dead space ensure high durability even with abrasive products all valves with a minimum of dead space play a crucial role in the chemical, pharmaceutical, cosmetics and food industries. This is because, particularly with fast-hardening materials, it is important to avoid deposits and residual products on the inside of the valve – between the ball and the housing. Otherwise, crystallisation and polymerisation can cause the ball to block, with the result that redirection or shut-off of the material flow is no longer possible. Residues of other materials can also lead to contamination, for example when the product is changed. ATEC GmbH has now developed innovative ball valves with minimised dead space that allow the safe flow of material in multiple directions and provide reliable protection against blockages – even with abrasive products, high pressures and extreme temperatures. B The state-of-the-art special ball valves, which ATEC manufactures and markets itself, feature a T-bore, which allows a flexible 3-way redirection of the material flow. The products are unique in that the cavities are filled out with half-shells made of a range of materials from hightemperature plastic to stainless steel depending on the product, providing reliable protection against deposits in the housing. They are suitable for temperatures up to 500°C and can also be used with extremely high pressure of up to PN 320. The metal ball valves, for which a special manufacturing process was developed, all have the highest level of leak tightness (Leakage rate test in accordance with DIN EN 122661 Leakage rate A = zero bubbles). This is a major advantage over many other metal ball valves on the market, because these only have “Leakage rate B”, which allows a certain amount of bubbles per minute. 126 PECM ssue 15 The ATEC metal-sealed 3-way ball valves are also characterised by a prolonged service life, a higher switching frequency, high flow rates, and high chemical resistance to corrosion with a resulting reduction in maintenance intervals. The innovative ball valves, which have already been successfully tried and tested by well-known companies around the world, are now in stock for all customers in Germany and abroad. They are also available with an L-bore and in horizontal and vertical versions with nominal diameters ranging from DN 15 to DN 250. 100% Made in Germany ATEC attaches great importance to the fact that without exception, every product is manufactured in its production facility in KleinWinternheim near Mainz, by its own highly-qualified specialists. Only in this way can consistent quality, optimum safety and a high degree of flexibility be guaranteed. ATEC is thus always able to respond to every customer request quickly. Perfect, tailor-made solutions in next to no time – guaranteed! Andreas Hampel, head of the technical department at ATEC told us: “We are a real problem-solver, and instead of mass production, we always deliver 100% tailor-made quality. Our customers value our flexibility, and our ability to supply individual solutions that m
