Technical designers always try to position pneumatic valves as close to actuators as possible, because shorter tubing lengths reduce the required compressed air by up to 20 percent. However, common valves are usually too large and heavy for handling applications. With AVENTICS’ new generation of extremely compact and lightweight Advanced Valve AV valve systems, engineers now have a lot more freedom and can arrange pneumatics decentrally, thus increasing efficiency.
Compared to the market standard, AVENTICS has halved the weight of the new valves by using resistant high-performance polymers and reducing the number of parts. A further plus: The required space has also been cut by 45 percent. How did they do it? Developers arranged the valve components at an angle and optimized the supply and exhaust channels, thus reducing flow losses. Users profit from a flow improvement of 40 percent, allowing them to substantially lower the supply pressure and boosting their energy efficiency.
The new valve manifold system also fulfills engineers’ demands for customized automation solutions. With 25-pin D-sub connection, manifolds can be configured in increments of 1 after the second valve position, and after the fourth valve position with 44-pin D-sub and Fieldbus connections. AV valves can control up to 24 coils with 25-pin D-sub connection, up to 40 coils with 44-pin D-sub connection, and up to 128 coils with Fieldbus connection.
Today, more and more users also implement different pressure zones in a single valve system to achieve further savings. The new valve systems allow up to ten supply plates for this exact purpose. Flow requirement variances are covered by offering both the AV03 size (up Cv 0.3) and the AV05 (up to Cv 0.7), and both valve versions feature a 12.5mm valve width. The AV03 and AV05 versions can be combined in the same valve manifold.
In addition to improving the energy efficiency, AV valves also fulfill expectations for simple engineering. The plug-in design makes valve interchange extremely easy. Users can connect the valve systems electrically using multipole or fieldbus connections, with integrated I/O modules, depending on their configuration. The wide range of I/O choices include: I/O blocks with M8 or M12 connectors, output modules with 25 pin D-sub, analog I/O modules, and digital I/O modules with spring clamps. Thanks to the option of directly connecting sensors to the valve electronics, fewer cables have to be fed back to the control cabinet. The AVENTICS online configurator allows a user to completely customize a valve manifold system and get a part number and CAD drawing immediately.
