PNEUMATICS 22 HYDRAULICS & PNEUMATICS March 2026 www.hpmag.co.uk Festo has expanded its VTUX valve terminal platform with a series of new functions and connectivity options that give machine builders greater design freedom, improved energy efficiency, and enhanced digital capability. Building on the highly cost-effective VTUX base system, the latest additions include advanced communication via Festo AP, new smart vacuum and I/O options, and new energy-saving valve functions. Together, these enhancements enable the creation of more compact, responsive and future-ready machines - reducing compressed air consumption, simplifying architectures, and lowering system costs. The VTUX was initially launched with basic capabilities to meet the broad needs of most volume users of pneumatic solenoid valve manifolds. Since its introduction, there has been a continuous roll-out of new features, making things even easier for users. The basic VTUX valve terminal is carefully cost-optimised through design and manufacture, delivering high flow rates and virtually unlimited modularity. The valve modules can be arranged freely and are compact and lightweight, saving time, space, and weight in the machine. The ability to ‘split’ manifolds cost-effectively without having to pay for additional fieldbus nodes means designers can arrange their layouts for ease of assembly and simpler maintenance. Crucially, the VTUX minimises piping run lengths, which can improve response times and cycle rates at the same time as reducing wasted ‘dead air’ volumes. However, the greatest benefits result from Festo considering not only how to mount and connect pneumatic solenoid valves across a machine but also the surrounding architecture. VTUX now uses Festo AP (Automation Protocol) to optimise digital communication. This brings flexibility, enables open architectures, and allows seamless integration of electrical and pneumatic automation. With AP, VTUX becomes part of a digitised automation platform, enabling sensor integration, advanced diagnostics and predictive maintenance through data exchange with the cloud in the Industrial Internet of Things (IIoT). Festo’s CPX-AP-I remote I/O system with IP65/67 protection enables real-time communication via Ethernet-based fieldbus. Seamless connectivity also supports all other technologies, such as IO-Link or direct fieldbus integration. A recent addition is the CTED multi-protocol node, which enables compact, flexible and cost-effective connections directly to all common Industrial Ethernet (fieldbus) hosts. Whether the system is central, decentralised, or hybrid, VTUX with Festo AP offers scalable configurations, integrated safety functions, and flexibility for the customer’s machine concept. Consequently, machines communicate more efficiently, grow flexibly, and meet the highest safety standards – from compact single applications to complex networks. The lightweight design of the VTUX means it can be deployed on the frontend unit, a portal, or a robot arm, enabling short and efficient compressed air lines. Innovative new features include optional individual input modules for ultimate flexibility and logical commissioning and diagnostics. The ability to specify one, several or all slices with a smart vacuum generator further enhances reach and flexibility. This option is particularly attractive in end-of-arm applications where reduced piping and cabling make assembly faster. Fewer snag and wear points, combined with the reduced footprint and moving mass, create significant performance enhancements. Performance and sustainability combine in the new Smart Switch Lite. With this option, a 5/4-way valve on the VTUX valve terminal enables the supply air to be switched off during cylinder movements. This saves energy and optimises the cycle time simultaneously. Despite the supply air being switched off, the cylinder reliably reaches its end position due to the residual expansion energy. In addition, the cylinder chambers can be individually exhausted and blocked, which enables precise control and greater flexibility. Reduced pressure in the end position ensures that the subsequent movement can take place with greater dynamics, enabling faster and more efficient processes. Commenting on the ongoing development of VTUX functionality, Festo’s GB Product Manager Jonny Mottram said: “VTUX technology is continuously evolving to meet the automation needs of our customers, and we have further exciting new VTUX features planned for 2026. I’d urge machine builders seeking to increase their machines’ performance while reducing costs to make use of the national network of Festo Applications Engineers. Their extensive try-out facilities can significantly reduce the time and risk of changes by thoroughly modelling and testing your solutions.” For further information, visit: www.festo.com/vtux Smart valve terminal expands automation flexibility Pneumatic upgrade improves production line efficiency A leading kitchen manufacturer was struggling with a series of outdated pneumatic backplates controlling its production lines for kitchen cupboard assemblies. Maintenance and fault-finding were challenging due to the absence of colour-coded pipework and a monitoring system. Health and safety were also a concern, as the original system had retrofitted safety components and lacked several key safety features. One of Camozzi’s premium distributors, Engineers Mate, part of the IADA Group, approached Camozzi for support with the replacement of three initial backplates, one air preparation set and two valve control backplates. Representatives from Camozzi Automation, including the technical application team, visited the site together with the distributor to meet the team, understand operational and safety issues, and discuss the customer’s requirements. The customer required three complete backplate replacements, including new valves, colour-coded pipework to support fault-finding, and as many additional safety features as could be recommended. The application team at Camozzi Automation suggested creating a comprehensive operating circuit and full schematic drawings with clearly labelled valves to facilitate machinery
