Alfa Laval introduces enhanced diaphragm valves

Alfa Laval has announced its all-new, extended range of Alfa Laval Unique DV-ST UltraPure diaphragm valves designed to make high-performance aseptic processing easier than ever. The enhanced, ATEX-compliant range is fully customisable and comes with slimmer stainless-steel actuators and lightweight cast valve bodies with optimised performance. “These valves are much more compact, yet deliver the same reliable, aseptic performance,” saidPawKramer, portfolio manager, valves and automation, Alfa Laval. According to the company, the actuators are 42 per cent lighter, 25 per cent more compact, and 17 per cent shorter in

height than most actuators, yet still deliver big on performance and energy efficiency. The new standard DV-ST actuator range shrinks the footprint of aseptic processes and boosts productivity. This versatile, space-saving new range of stainless-steel actuators operates at a wide range of pressures. Options include a stroke limiter, economical valve position indication, and compre- hensive automated valve sensing and control. Smaller seat sizes on the lightweight, ASME BPE-compliant Cast OP valve bodies optimise flow to ensure the same performance as well as lower total cost of ownership, safe, simple

devices along the line. It is user friendly and offers excellent signal purity. The modular concept for testing long products together with the licensing system for the ELOTEST PL600 allow for a short changeover time, a straightforward exchange of the testing techniques and an upgrade of the eddy current testing instrument, which is possible at any time. ELOTEST PL600 has been supplemented by a 19" (PL600/R) and a compacter 9.5" (PL600/ RC) remote version for integration into automated systems. The EloLine software, which is used during the testing of long products, has also been developed by Rohmann. It serves to visualise and record the

acquired results. Serial part numbers, batches, serial numbers, length of the tested parts and the name of the inspector can for example be saved in the data base. A detailed test report for every tested part or a report on a specific production batch can of course be printed out. Rohmann not only develops and manufactures testing instruments, but also the pertaining testing technology such as rotors, yokes, coils and sensors. The customers are furnished with customised solutions from one provider.

The company, which is situated in southwestern Germany, offers a modular concept for materials testing with eddy current. When different testing techniques such as rotors, coils or yokes for magnetising and demagnetising the test piece are used in the production line. Whether crack detection or material mix-up, ELOTEST PL600 displays the test results of different testing stations, which in the past required several
